I just noticed something. On the microsoft update page, you can view your update history. Everytime I shut down my computer it tells me there are updates to install, which it downloads, etc. and then shuts down like it should. I just looked at my update history, and the only updates that have not failed are 'windows malicious software removal tool'! All of the other updates (except for 4 dated 9/1/09) failed. That's 500 updates that have not worked! Is this the virus causing them to fail? How do I fix this?
