When I updated an XP SP3 from 2014.9.0.2013 to 2014.9.0.2018 Avast sheilds didn't come on - no antivirus protection. Error message: "AAVM subsystem detected an RPC error"
Avast dates showed I had till Nov 2014, yet 0 days remaining. I tried re-registering twice but no help.
I hadn't added or removed any other antivirus on this PC..just updated Avast from version to version for several years. Due to this problem, I've installed windows defender so I'm not totally unprotected. I also have 'on demand' malwarebytes & SuperAntispyware. All 3 play well with Avast on other XP PC's.
I've read several posts about people going thru multiple Avast uninstall and reinstall cycles to solve this problem. I'm not going down that road. I'll try repair strategies & I'll remove and reinstall once if I have reason to believe that will solve the problem. If it doesn't, I'll remove Avast completely and try a different AV.
All suggestions for repair appreciated
