You've probably realized this by now, but that's a pretty horrible idea. If you want to try to speed up a well-used PC, start with a defrag.

You could clean it up some, but really, you'd never know if you got everything or if there was still some malicious software left lurking. If you're going to fly without antivirus software, you should at least have NoScript and AdBlockPlus to protect your browsing a little. I use those plus AVG, and never seem to pick up any malware on my PC. Also, from people I've talked to, AdAware has fallen out of favor somewhat. My friend raves about SuperAntiSpyware.

So anyway, I'm with Whacker. Backup any files that you can't live without, and then format everything and reinstall.
