This is such a bad idea on so many levels. For example that ZEROACCESS rootkit is quite hard to remove. And we have those trojans that allow a lot of OS damage that even if you remove the virus/trojan/rootkit, the damage remains.
Your post makes me think you might be new to this work.
I suggest you think about prevention next.
I need help infecting a training computer at work to train employees on proper virus removal techniques. I was looking for a way to get a malware or virus that would be similar to the Windows xp recovery virus. I have had no such luck in finding anything, so any help would be appreciated.
