This is not a virus warning, but an antivirus warning.
I've been using McAfee Antivirus and their other products on my computers for as long as I have owned one. Their antivirus software has always gotten high marks from Maximum PC Magazine, which is a source I trust and highly recommend.
Well tomorrow I'm uninstalling McAfee from my computers. A month ago I noticed my checking account was short and found out McAfee had hit it for my yearly subscription. I called them up and they confirmed that I had not authorized auto-renewal and said I would have a refund in 3-5 business days. I was furious, explained what a shitty deal that was due to their mistake, as if giving them a piece of my mind would do any good.
That was bad enough to sour me on the company, but today was enough to set me on a campaign. Today I found out that a couple of days ago they did it again - they made yet another withdrawl from my checking in an attempt to get me signed up for another year. So I called them up again and was calm at first, but by the time I was finished I am sure they will not only remember my name but have nightmares about me.
So if you have ever purchased something from McAfee with a debit or credit card, make sure that info is not stored in your McAfee account. Better yet, if you have never purchased from them, don't ever do it!
