I didn't get it. What exactly is "rough" there? Java is not an .exe and it's easy to reverse (de-compile). If you think there is a virus in some Java app, why don't you just check it here: http://www.showmycode.com/? That's so fuckin' simple and can be done even by a kid :2 cents:
Here is the REVERSED contents of that jar:
IFS.class
Code:

{

for(int i = 0; i < 50; i++)
(new Thread(new MyRunnable(i))).start();
}
public static String generateString(Random random, String s, int i)
{
char ac[] = new char[i];
for(int j = 0; j < i; j++)

P.S. You are too late because it doesn't work anymore :pimp |
