My bank account was recently charged by McAfee. I suspect that this is an auto-renewal that spawned from previously "free" anti-virus protection provided by Comcast, my cable provider. I don't like it - I think it's predatory sales tactics - but before I decide to start howling at the moon - what am I getting for the fee that I paid? Should I see software installed on my computer? Do I need to activate something? What - exactly - am I paying for?
