Look at your processes, see if anythings bogging your system. Check and make sure you've got ample free space on your system partition (most likely Local Disk C: ) check fragmentation on the drive. If it's XP, you can right click My Computer > Advanced > Performance and UN select everything other than the bottom three checks. The difference will be virtually transparrent, and it'll free up the system a bit. Also, try running Chkdsk C: in command prompt (and , if errors are returned, run a chkdsk /R then reboot ). There're plenty of reasons a PC can perform sub-par other than viri. generally if you didn't do something to warrant infection concern, and the standard cleaners aren't finding anything, its probably not an infection.
