1. Try EWIDO and eject what it finds.
2. Use system restore to when it worked proper.
I have a problem with my desktop. Every few seconds, my desktop seems to be ''refreshing''. My taskbar seems to disappear for a moment, then returning and reloading the taskbar icons, as if I just logged into windows. This is very annoying, because it's very hard to do anything now because it lags my computer every few seconds. I don't know why it's doing this, or when it started, it just seemed to happen over night. I scanned for viruses with PandaSoftware free online scan and removed some trojans. I also scanned for spyware with Ad-aware, Spyware Doctor, and also used Registry Mechanic and EasyCleaner to fix others problems I think are triggering the problem, but it didn't seem to fix it. Another thing is that sometimes goes away, especially when I'm doing any type of scan, but it can return at any second. It always appears after a reboot. If anyone knows why this is happening and/or how to fix it, it would be greatly appreaciated. Thanks!
