the update broke online security for FireFox 25 on my Windows 7 64bit system. It shows as incompatible. repair, uninstall, go back to the previous version it still is broke. It has also somehow installed a monitor in action center you cannot turn off or ignore without ignoring both the firewall and spyware.

System restore was the only fix. I guess I’m going to have to turn auto-updates off in Avast, and wait to see what problems the updates create before updating the software.
