What are those? Read http://www.doxdesk.com/parasite/
These are not noted by today's Antivirus programs, but do put quite a load on the system.
After you've tossed off those, consider reviewing Optimizing Windows at http://www.aumha.org/articles.htm
I have a compaq computer (which I don't care for), and for the past year, my icons get fuzzy, disappear, and fade. This isn't just on the desk top, it's also the quick launch icons, the icon's in the windows taskbar, programs (I can read the words, just the icon pictures get weird). I've called compact (ha ha), the guy told me to change my color settings to 250 then apply, then change it back. This works for about 30 minutes. Anyone else have ideas? I'd really apreciate anything. Also, I don't have a worm or virus.
