I am now getting a warning from AVG about every 30 minutes even when my browser is not live, that "backtothefuture.biz" has been terminated and its because its infected with URL:Blacklist 
This never stops. 
I have also noticed my location on google maps is not in the right place and i am not using VPN.
I am concerned i have a real problem here but AVG does not do anything about it.
any clues?  
I did suspect it was a VPN virus problem and ran a scan for this and nothing showed up, so its possible its a mis detection by AVG?
