I have a Dell Dimension 8100 512 MB of RDRAM running on Microsoft XP.

I was using my computer today and suddenly my mouse started having problems. The clicker (arrow thing I don't know how you call it) would move EXTREMELY SLOW and would sometimes not move at all. When I clicked on thins like to make a window bigger or to close it sometimes it wouldn't perform the action. (ex. I click on FireFox "x" to close it but nothing will happen) Also, EVEN if I don't click on something it will automatically click on it and get STUCK. I checked my mouse (wireless Logitech mouse) and re-installed the software and checked the batteries and all and I STILL have the problem. I scanned w/ ewido which found three viruses. I restarted and nothing. I ran AdWare and Spybot Search and Detroy - nothing. I ran AVG which found two trojans, one it deleted the other one was left intact apparently. The problem persists. I do not know what could be affecting the mouse or even if it's a virus.

Any help would be appreciated.Disable System Restore, re-start in Safe Mode & run the scans again.
Make sure your scanners are uptodate first.Well I did exactly what you said (are the scans supposed to take 2x as long in safe mode? Beacuse they took WAY longer than usual) and nothing came up. The mouse has been working fine so far (10 minutes) but one thing I did notice is that there have been several changes to the REGISTRY ( I have Kerio personal firewall and it shows me the changes) I can't exactly read them because they pop up too fast but something changed on my msn, aim, and some tmeeh thing.

I hope the problem is gone.
