Not sure how close I am but I remember getting a pretty wicked virus (think it was a combination of trojan horse and virus) that crippled my system utilities. I couldn't defrag, I couldn't open the task manager (I have XP Pro) etc. Not sure we're talking about the same thing here but I would try visiting:
Follow the directions to let both of these websites run an online scan of your computer. Both will need to install a control onto your PC, this is OK. Even with an active and up-to-date anti-virus program on your PC viruses can be overlooked. (Afraid I had MANY problems with Norton doing this).
In every home user's PC Toolbox should be:
Anti-virus (active scanning and auto-update definitions, need a great free anti-virus, I like Avast!)
2-4 Anti-spyware programs (Spybot S&D, Ad-Aware, Spyware Blaster, and Microsoft Antispy are a good start)
Anti-trojan (active scanning and auto-update)
Firewall (free! Zone Alarm, Tiny, Kerio)
There are a multitude of other products and cleaners out there that are well worth the trouble. But the ones mentioned above should be considered the minimum. Anti-virus programs don't do the same thing as anti-malware and anti-trojan programs so you'll need them all.
My guess is you've got a virus or combination of viruses that the online scan engines will find. Panda does a FANTASTIC job of removing most of these little buggers but I would venture to say you are going to need a removal tool (readily found on the web).
If my hunch is right your next step is to open your anti-virus program, make sure it's set to automatically obtain definitions, make sure it's active scanning depth is high, or "deep scan" and make sure that you have the Advanced Heuristics checked off.
Good luck, let me know how you do.
I have a 5 yr old dell computer with windowsme.When I check it is showing memory 78% free.
It doesnt want to reboot and the scandisc and defrag wont work.System restore only shows today for a restore point.I had problems a while back and on the phone tech guy told me how to get a restore point by typing in something in the run box,but cant remember what that was.
Usually if I have problems I just do above tasks that wont work and it is fine.I have cleared my cache and aol spyware checker says I dont have any spyware.
Any assistance will be greatly appreciated.Not too technical please.
