My Dad's Emachine desktop runs XP and he normally didn't have to log in. It would boot right up to his desktop whenever he turned it on. He got infected with some type of trojan this weekend (detected by spybot, name unknown, he didn't write it down). However he did remember that it said it could not remove the infection because of files that were in use and that it would require a restart and could it run on bootup. He told it ok and when it booted back up it came up with a user icon called Owner and said that he had one unread mail message. When you click on the icon to log in it says "logging out" and stays at the log in screen. I tried to start it up in safemode but it goes through the motions and then returns to the menu where you choose safemode, normal, etc.
The OS was preinstalled so he has no installation disks other than the factory restore partition so I can't try to repair. Is there a virus scan or other tool that I can install on a USB drive and boot to it and run a scan?? Thanks!
