Bitdefender Total Security 2015 in my opinion and quite a few reviewers the best one. They gave me a bunch of copies to give away free last year. Could probably find a coupon for ya if ya wanted it. If ya did pay full price the trick is never renew early and when ya got about 2 months left they will send ya a renewal email for like $34.95 so 3 computers for $34.95 ain't bad.
