Computer running 32-bit Win7 has version 7.0.1367 on it. Every day, it tries to update to the new version, and reports an error pop-up. Attempts to do it manually say that it worked, but when you go in and look again, the program still shows the old version.
Uninstall from safe mode using this, reboot install nev version. http://www.avast.com/uninstall-utility
