Looking for a virus - like the kind that spreads all over your HDD and ruins/destroys a computer. Are there places to get things like this? I'm doing development and testing on a virtualized platform and I want to create 4-5 instances of XP & Windows7 and then infect one to make sure that my firewall and virtualization is setup properly. If the virus takes down the whole machine then I screwed up somehow - if the virus only takes down that one instance/image and the rest are fine then I'm comfortable with the situation. This will be in a 100% controlled development environment on an isolated ISP. Thx for thoughts & suggestions.
