Has Avast! been disabled in any sort of way? Services not running? Shields not working? If you are having issue with detection report them
Here.Are you experiencing Non-Booting windows issue? Similar
to this case?Need I say anymore???
Yes, it would help if you were to explain why you are unsatisfied.
