JohninKansas may be able to help.

Norton worked for a while with me, but I developed problems after an upgrade that they could not seen to help, so I switched to McAfee. After a while, it started to take hours to update or the updates never completed loading. I spent two half days bending ears with their technicians in India, and no solution (the technicians seemed good- their solution would work for a short time, then the same problem again). Although I had months to go on their paid version, I quit.
I have Spyware doctor and Antivir now, and they seem to work well. However, when the paid Spyware Doctor runs out (or sooner), I will get the protection my broadband cable supplier offers (free). No one here in my city seems to be having trouble with protection through this cable service.
