I would restart in safe mode (F8 while starting up) and then re-run your anti-spyware programs (spybot, adaware, etc). Running an antivirus client may also help (avg, avast, avira are all good, and free). Once you're done, reboot into normal mode.

EDIT: If you want to use the internet in safe mode, do the safe mode with networking option.
