What good antivirus and internet security programs do you use for Win7?
When I was in XP Pro, I used Norton 360 v1.0. Now in Win7, I'm using AVG internet security 9.0.
I'm using MS Security Essentials (antivirus) and Spybot: Search and Destroy. They're both free. MSE is quite light compared to the Symantec Endpoint Corporate I was using.
