After I updated to Avast 7 version 7.0.1426 my email is constantly locking up. I am currently running Windows 7 64 bit, Outlook 2007. The error message I am getting is as follows:

I fixed this problem by going to Trust Center in Outlook (while logged in as Administrator, which means selecting that option by right-clicking on Outlook on the Start Menu), then disabling the Avast Anti-SPAM plugin. I also disabled a bunch of other plugins that have made Outlook run much faster!
