..reinstalling Service Pack 2 from the link below? Download the file to a clean computer, then burn the file to a CD.. TRansfer it to the "problem" machine and run it . It should repair any problem files. (It's a large file, about 266 MB, so you'll need broadband to download it.)
Next, download, install, update, then run the free AVG Antispyware tool from the link below:
Ewido/AVG Antispyware 7.5 Tool
Hope this helps.
