|muvendrann, slowness is a common complaint and can have many causes. I'll address a few of the more common. Yours? Dunno.|
First thing I'd do is make sure there's no worm/trojan. Be aware that a virus and a Trojan are similar, but not the same. Many times, an AV detects one it can't clean, other times, it gets missed entirely.
If you need to clean one, Superantispyware (info only. I’m not paid for recommendation) can do the job and you can get it free @:
among other places. They have a Vista compatible version if needed Dunno about Windows 7..
If it turns out that you need to use it, be sure to update Superantispyware prior to running and disable 'restore' (restart after cleaning) so the nasty doesn't get put back. They just released a new update recently and it changes all the time. Things are in a constant state of flux.
The restore thing is critical. May not be your deal at all, but won't hurt anything to try.
Next, I'd defrag. A lot of scattered file fragments can significantly slow HDD access.
Next, I'd download/update/run CCleaner set to delete 'index.dat' and temporary files. If you need CCleaner, get it free @:
Next, take a look at your start up menu in your control panel. Quite a few software writers think there's no possible way you could exist without their latest masterpiece , so they add it it making initial access slow.
There're others, but those are very common.
