Kaspersky Anti-Virus 2013
Full user review
"Can be gotten cheaply if you know what to do"
As good as there is on the market today.Definitely optimized for those running Win 7and multi-core processors
Doesn't run great on xp,but then again xp should be retired by now.
I have heard many say that it is expensive,but you can use license keys as far back as 2011 model year on 2013.Current rate on the Kaspersky internet security 2012 on amazon.com is 15 bucks aprox for a 1 user license and under 20 for a 3 user license..Just download 2013 from the kaspersky website and install as a trial while you wait for your key to arrive..then when your trial is up install the license key from kaspersky 2012 that you purchased from azmazon and voila.
