AVG has scammed me out of $500 plus a year in subscriptions I never signed up for. When I tried to cancel I was told I had to pay $299 to upgrade my OS so they could take the software off my computer to stop the future billing. the customer service guy, David, yelled at me, told me I didn't want to understand and I was wasting his time. He kept saying you will be happy paying $500 for subscrpitions every year!
