The free version of avg is bad.I used it a year ago.AVG itself says that the free users don't get priority updates.So the paid version of AVG may not be that bad.( I did not use the paid version).as you have got a free license,I will say that you should give it a try.As it is free for you,so you can give it up anytime.Who knows,may be AVG paly well on your computer.best of luck.
