crsaj, I'm betting the windows defender that would not start up was the beta version. you need to go to the microsoft site: http://www.microsoft.com/athome/security/spyware/software/default.mspx
and download the latest version of it. ( I just had the same problem on a friends computer.)
Good luck.
beta version expired Dec. 31
