Are you a Facebook user? Here is a link to a free 6-month subscription of McAfee Internet Security 2011, complimentary for all Facebook users: http://us.mcafee.com/root/landingpages/affLandPage.asp?affid=773&lpname=272multi&cid=70235 If you are not, you can register and receive that nice software as well. Why McAfee? Well I found it interesting to see in the last issue of Russian computer hacking magazine (http://www.xakep.ru/articles/magazine/xa.asp) a heuristics test of Kaspersky Internet Security 2011, Eset NOD32, Avira AntiVir, and McAfee (all latest builds).
In seven runs the guys tried one simulated trojan, modifying its code each time. Having put aside all details of the trial and to make the long story short, at the end McAfee was the winner, KIS2011 was second, and Avira with NOD32 were third and forth accordingly. But all the antiviruses failed at the end anyway, that is why the article is called ” Heuristics, which we f*cked”. I put the low-resolution screenshots below, if someone is interested.
