Using Avast 6.0.1091 Definitions up to date - no known issue and no malware on
system. Only out of curiosity, I ran the scheduled boot scan and sure enough
after it finished the “This Copy of Windows in not Genuine” appeared in the
right-hand corner of the screen.
It is pretty simple to fix if you know how however this should not happen and
seems to have been a bug for quite a while.
Any fix so the Boot Scan will not cause this issue?
Yes it is repeatable. I recommend Avast often and others have told me
they had the same issue. There are many instances of this happening in
this forum.
