Respected research firm NSS Labs conducted a study on the effectiveness of the most popular antivirus software.
As it turned out, of the 13 tested solutions only two products were able to block more than 80% of the known exploits. This is rather alarming result as antivirus vendors usually promise complete protection from known threats.
According to the results of comparative testing, package Kaspersky Internet Security 2012 blocked 92.2% of known threats, but the package Alwil Avast Pro Antivirus 7, which became the second most effective, managed to overcome a 81.9%. The third in this test was a package Symantec Norton Internet Security 19 (74.1%), fourth place went to package AVG Internet Security 2012 (73.3%), and the fifth – a package of ESET Smart Security 5 (70.7%). Then there are products such as Trend Micro Titanium Maximum Security 6 (69,8%), McAfee Internet Security 11 (65.5%) and Avira Internet Security 2012 (64.7%).
Interestingly, the popular package Microsoft Security Essentials blocked only about half of the threats. Close to him approached package F-Secure Agent 1.57 (44,8%), and closed the list of packages Norman Security Suite 9.00 (42,2%), Panda Internet Security 2012 (38.8%) and Total Defense Internet Security Suite 8 ( 34.5%).
In connection with such unexpected results is worth mentioning that according to research company OPSWAT in September of this year, Microsoft controls 27% of the antivirus market, ahead of Symantec (16%), Avast (11%) and AVG (10%).
Feature of the study was the use of NSS Labs only known threats, but do not attack “zero day” to test the effectiveness. As it turned out, many popular antivirus programs are unable to detect and block threats, which were recorded and described for several months, if not years, ago. Thus, according to the experts NSS Labs, insufficient protection use from 65% to 75% of users around the world, and in North America the proportion is 75% to 85%.
