I get this error every time I try to update anything. I recently bought an upgrade and can’t even use that because of these errors. Avast says everything’s ok, but to me it looks like I haven’t received any definitions since August 2014. Please help me to fix this. I don’t even like thinking that I’m not covered.
Well right now its Avast Free, but I had bought the upgrade to Pro. It won’t even download the new Pro version either.
Current version it says: ffffff-ff but it also says everything’s good.
OS: 64 Bit
The only other security that is used is the windows defender.
I had this pc built for me and it came with Avast. I have had Kaspersky in the past though.
I like Avast because it doesn’t interfere with my gaming.
Thanks for responding 
Eddy
