You have 2 choices. Both the Antivirus and the Security Suite (which includes the firewall). Both these products are Retail and Final.
2. Norton 360 V3.0 Beta
This is a new Beta which Symantec claims works with Windows 7. I had terrible experience with their product (V2.0) and even more when they beta it in Windows Vista. I passed on this. How about you?
Kaspersky has a high accuracy, but can be a bit noisy in the responses required. Security wise, I never had a doubt its one of the best. But it may not be for everyone. Still, they are one of the first again to office Windows 7 support. Although it did not mentioned specificly, I believe the full Security Suite is compatible with Windows 7.
