1. The virus CANNOT spread through JJ2, the only way is the method link pointed out about replacing it with a level blah b lah, but it'd be difficult to do.

2. I don't think it'd attach itself to programs, for various reasons that I'm too lazy to type

3. Overlord, Eagle and Krezack don't make viruses. Overlord is not that type of person, nor is Eagle or Krezack.

Use mscfg to take it out of startup. It shouldn't hassle you then.
