|BuddyA, first thing to do is be sure you don't have a nasty (virus, worm/trojan, etc.)? 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. WARNING! FYI, a full scan on mine takes over an hour.) 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 or later.
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.
Slowness is one of the more common complaints heard and it can have a number of causes. I'll enumerate a few of the more common and we'll hope that hits you.
Cable access? The number of folks trying to access the net at once can slow things down. Get up in the middle of the night and see if it's faster. If so, learn to love it (the slowness), it's them not you.
Speed depends on memory and a lot of machines are right on the borderline when it comes to meeting required minimums so any added 'memory hog' has an adverse effect. Add memory?
Sorta along those same lines is your startup menu. Lots of software writers think there's no possible way we could exist without their masterpiece so they put it in the startup menu. That usually only causes slow booting, but ... Take a look at what you have running in the background and be sure there aren't extras.
An overzealous firewall reading each item over and over can significantly slow things. Kinda along those same lines are temporary files. Search for *.tmp,*.chk,~*.*, .chk (c/p so there’re no errors) You should only have 1 file containing your currently active files. Delete any others found (tip: select all and delete. It’ll tell you which is active and can’t be deleted.).
A common ailment is a file called 'index.dat'. It gets read every time and can take quite a while if it’s too bloated. It's like a log file and keeps a record of every site you visit on the web. Empty, it's 32K, but it can grow HUGE. It's a protected file and can't be deleted by normal methods. CCleaner (free @: http://www.ccleaner.com/) can get rid of it when it’s ticked (not to worry, it gets rebuilt EMPTY on the next boot.). May not be your deal at all, but won’t cause any harm to try. I run it often (daily).
There're others, but those are some of the more common. Suggested further reading: http://speedupslowcomputer-shelly.b...
