Tracking cookies (third party) from the likes of fastclick are found on many sites you visit, even those you might think are above such things. Use Ad-AwareSE or Spybot periodically and clean them off your hard drive. Consider also changing your browser's setting to "always ask before accepting cookies," or whatever it calls it.
If you have Spybot on your computer, use its start-up tool to compare what is listed with the BC Startup Database. The latter will tell you if the application is needed, optional, or should be killed.
Perform a little routine maintenance by deleting or moving old files, vacation pictures, games you don't play, saving what you want to disk, and then using MS disk cleanup; you can then run checkdisk/scandisk and defrag in safe mode.
