I've been having some internet connectivity problems lately, and I believe it's due to some nasty spyware. I've already gone through all the steps to correct this (checking my DSL speed, anti-spyware scans, anti-virus scans, doing it all in safe mode, even reset my winsock.dll, etc.) but I'm still having problems with slow browsers. So now I think I'm faced with reinstalling Windows XP. My question is, should I do a format & reinstall, or is it better to reinstall Windows over my existing version? I have a Compaq Presario, and it comes with a Recovery CD. Any help is greatly appreciated!
