Hi - Just a heads up. I installed Zone Alarm Pro (9.0.136.000) on Windows 7 RC-1 Build 7100.

I disabled Microsoft Security Essentials before I installed ZA Pro. After rebooting and re-enabling Microsoft Security Essentials, the PC froze.

I booted to Safe Mode, disabled Microsoft Security Essentials, and rebooted.

Windows 7 and ZA Pro are now running smoothly.

If I re-enable Microsoft Security Essentials, the PC will freeze again.

HTH

P.S. I know there is no official support for Windows 7 until it is officially released.
