Have been using the free avast for several months now and everything was fine, but about a week ago I ran into a problem which I still dont get. Basically, the problem is that in the tray of the monitor the Avast icon is crossed out red. I hovered the cursor and saw the system wasnt protected. So everytime I try to start the protection - nothing happens. What to do with that?? :-\
