I clearly stated that I uninstalled Mail Shield, so there is nothing to check/uncheck. Only File System Shield and Web Shield.

I used avast! Free Antivirus 2014.9.0.2006 before upgrading to avast! Free Antivirus 2014.9.0.2007. Before that I used avast! Free Antivirus 8.0.1497. There was no problem in 9.0.2006.

I tried repairing; it didn’t help. As for uninstalling and reinstalling: that’s a bit overkill imho. It doesn’t bother me that much… Also, I don’t believe that will solve the problem… I’ll just wait and hope this will be fixed in the next build.
