2. Check your Anti-Spyware is upto date, then run a full scan.

Visit the MS update site to check:

5. If it's still not running, assuming that you haven't changed any settings in your modem/router, go through the Networking Wizard under Start > Control Panel > Networking
6. It's screwed. Throw it away and start again
