Windows Defender

In case you didn't know....
This is a new download(beta) from MS that I hadn't heard about. Replaces MS Anti-spyware. I think it's got a little bit of virus and phishing control in it too. Integrates well with SP2 security.

I got it too and it seems to be playing well with others.

I liked MS antispyware more, the icons were nicer to view, and setup was easier to navigate. This one is almost so straight forward its hard to find any actual settings.
