[8.965] portable apps blocked when End Point is installed

Hello,

I've installed the End Point and afterward none of my portable apps are working. Firefox v12.0 and Thunderbird v12.0.1. Nothing shows up in the End Point console as having blocked. I decided to disabled all Sophos services and reboot, then both portable apps start working again. What is the correct and safe way to remove the end point?

1. Sophos Anti-Virus
2. Sophos AutoUpdate
3. Sophos Management Communication

Thanks for any suggestion you can provide.
