One Google search later, and here I am. Apparently, there's been a lot of cases of this virus lately. I see a lot of Sirefef.B and Sirefef.Y here, but mine is Sirefef.R (virus) and Sirefef.AH (Trojan). Like many before me, I saw that WSE stopped working. Unfortunately, I ignored it until I found an unknown program running in my system. I reinstalled WSE, intending to scan said program to see if it was malware, and WSE detected Sirefef instead. Now Windows fails and forces a restart after a minute whenever I try to start Windows normally or tell WSE to remove it in Safe Mode. I have no logs or anything like that right now, but if it helps, I'm running Windows Vista 32-bit SP2. Help would be appreciated, since I'd like to get this PC up and running again for a huge game update I'm looking forward to and an art project I'm working on, and I'd prefer not to follow Microsoft's advice of reinstalling Windows.
