Have used Aol for at least 8 years.
My first AV was Dr Solomon -taken over and by MacAfee and left without contracted updates, just an offer to sign uo with the new owners!
Bought an AVG CD, soon found that a free version existed and added ZoneAlarm also(free version).
Have not looked back or been troubled since.
My sour advice would be
Download AVG Free and Zone Alarm but DONT install
Then come offline and do your best to be rid of every trace of MacAfee, lots of scouring and reboooting.
Now install AVG and the free version of Zone Alarm.
Go back online and update both of these.
