I have run AVG virus checker, Ad-Aware spyware checker, a registry cleaner (Eusing), defragged the hard drive, deleted temp files, cleaned the IE history, but the PC still runs slow. It’s got a decent spec, so is there anything else I can do to boost it’s performance?

Thanks

eusing ccleaner and http://diskcleaner.nl/ and windows advanced care v2 am i ok using this lot as they are all freeware

I need a free registry cleaner. The registry cleaners I currently have are:

CCleaner
Eusing
Abexo
Advanced Windows Care
Tweaknow
AML

Yes I know I have a lot, but each one finds different errors, so I guess I have more errors on my computer (plus its gotten really, really slow and I have 3.5 GB RAM and a 3.2ghz dual core processor and my other windows 98 computer runs faster than it).

So anyways thanks if you know of any other free ones!

Have used: AVG, AVIRA, ADWARE, CCLEANER, CYBERDEFENDER, EUSING and others. But my comp is still slow. I think I might have downloaded something infected or downloaded some malware and I don't know how to get rid of it.
