We had Avast for the past year, expired, tried to reregister, didn't seem to work. Tried BitDefender, didn't like it, tried to get back on with Avast. Seemed to reregister last night, got license number and put it in. But then there was the red mark on the blue ball. Did what it said, except under programs there was no "repair" with add/remove programs. I think my husband uninstalled it today as it is not there now. I deleted BitDefender, downloaded Avast again, got a license number, put it in, same thing. It wasn't in programs, so downloaded it again, still not there. Says it's there, got a license number, but still have the red mark and it's not working. Can someone please tell us what to do? Thank you.
