I was trying to undate my AVG defintions and I received a information tab stating to make sure your firewall isn’t blocking AVGinet.exe. I set up components and applications to allow all instances of AVG. Rebooted and still blocking AVG updates. After I exited out of the Comodo firewall it finally updated. Thought I’d share if it hadn’t been posted somewhere.
Did you try skipping advanced security checks for the AVG file?

Also, could there possibly be a blocking rule hidden in the registry?
