MRG Effitas is a UK based, independent IT security research organisation which organizes an ongoing so called flash tests series. The purpose is to assess how security applications react to zero day threats. This is very useful as new malware usually spreads the most within one week of its release.
Since June 29th, 18 different security programs had to compete with a total of 120 brand new samples. Only three of the probands were able to show a clean sheet with a detection rate of 100% – first of all Emsisoft Anti-Malware with the strong combination of a dual-engine signature scan and behavior analysis.
