Meeb,
The whole reason this thread was started was because you had a bunch of viruses and now parts of your system do not function properly. You have been fighting with this for over 10 days since you posted here. (My guess even longer before you posted here.)
Do yourself a favor and spend the 10 minutes to an hour (depending on the speed of your computer) and do a clean install of your OS. You will find, not only does it work better but it will run much faster too.
Take Care,
Richard
