I'll preface this post by saying: I'm not a computer expert, this is just my experience and humble opinion. In the past I bought name brand Antivirus software, installed it on my computer and then every year before it expired it would renew automatically because they had my credit card on file, yes it was convenient but it was getting expensive....$80 every year. I started seeing deals where you could buy the software and get a full rebate, so now I buy a brand new one every year, I get it FREE every time because there is always a rebate for the full amount or partial amount on some. The only downside is that you do have to reinstall every year when the old one expires but I'm willing to do it. I find great rebate deals on software at Frys.com and they usually offer free shipping so I don't even have to spend gas money to go buy it, you can also check Newegg, Staples, Office Depot for rebate deals.
