I started getting this error awhile ago and (stupidly) ignored it until i noticed i couldn’t update avast anymore. I tried repairing avast under the control panel uninstall/repair options and as it was repairing it updated my avast but my firewall wasn’t working anymore. The error was still popping up aswell.
So i uninstalled avast using their remover and reinstalled it and tried updating it to the 2014 version but it says my program needs to be 1995 or older (really???). On top of that it now says my subscription has expired!! Ive only had it since Sept of 2013!
The error is still popping up after all this too.
