Having recently upgraded to BB with Aol, I asked if it was OK to ignore Aol's freebies and continue to use the programs that I was used to using, AVG, ZoneAlarm and Spybot.
Aol's answer was Yes.
To use their stuff is a matter of requesting downloads. I think you may have items which have crept in out of the woodwork unbidden! ........If so I suggest you uninstall whatever you don't trust and load whatever you are happy to use
What did trouble me for a few days was the persistent popup of some spyware claiming my computer was infected and download our remedy OK ?? ........ NOT OK and the remedy for that was to block popups using the wee tab at the bottom right of the Aol page.
