I'm running Windows XP Professional, and I've had a variety of problems: the first symptom was my web browser shutting down when accessing certain sites, eventually followed by a message saying that the computer will shut down in 1 minute. My mouse is slow as is the whole computer. I've run AVG free, Microsoft Security Essentials, Stinger, SuperAntiSpyware, and now I'm running Avast. All found trojans and other worms - and still the problem remains. Here are some of the latest bad guys found by Microsoft Security Essentials: Renos.JV, Renos.JZ, Vobfus.F, Yabecter.A, Chepdu.P and Votwup.B . Any ideas what I should do? Thanks!
