A recent update to both the paid-for and free versions of AVG Antivirus has caused one of the above error codes to display and SuperNova fails to magnify the screen.

UPDATE 25 August 2016: AVG have now resolved the issue in the latest virus definitions update. Please update AVG to the latest virus definitions database then restart your computer.



This issue has been reported to AVG who are currently investigating. The only workaround currently is to remove AVG and use alternative antivirus software.
