I had a couple of viruses that wouldn't go away; I currently use Windows Live OneCare for virus protection, but it is apparently not getting the job done. I downloaded the latest free home edition of Avast (4.x), scheduled a boot sector scan and restarted the computer. It found two trojans; in both cases I selected the option to move the viruses to the chest.
When the scan completed, it pulled up the background picture for my desktop and stopped there. I can ctrl-alt-delete my way to task manager and restart the computer, but I've tried a couple of times and my desktop, launch bars, Windows menu, etc., are not coming up - just the background picture. (I'm typing in on another computer, obviously).
Any thoughts or ideas? Thanks!
