(LiveHacking.Com) – The latest set of tests performed by AV-TEST, an independent IT security and anti-virus research institute has shown that Microsoft’s Security Essentials (MSE) can only detect 64 per cent of zero-day threats when running under Windows 7. This is down from 69 per cent in the previous round of certification tests, which were carried out in September, and a drop of 26 per cent compared to the 80% result achieved by the product in June. As a result of the dip in performance MSE has lost its certified status for Windows 7, something that no other anti-virus product managed to do!
MSE is Microsoft’s free anti-virus package for home users and businesses (with up to ten PCs). During October’s tests AV-TEST gave MSE 4.0 and 4.1 a score of 1.5 out of 6. This very low score is down from its previous score of 2.5 out of 6 mainly due to the 64 per cent zero-day detection rate. The average zero-day detection rate is 88 per cent.
This doesn’t mean that the software is completely useless, in the “detection of widespread and prevalent malware” category, MSE scored 100 per cent (which is actually also the industry average). What this means is that for common bits of malware PCs are very well protected by MSE, the problem is with its protection against 0-day malware attacks (including web and e-mail threats).
This isn’t the firs time MSE has lost the AV-TEST certification, it also happened in September 2010. To be fair to Microsoft, although it was the only vendor which failed to achieve certification for Windows 7, four other products missed out for Windows Vista and two for Windows XP.
“Microsoft prioritizes protection based on impact and prevalence of malware affecting Microsoft customers from a global perspective,” a Microsoft spokesperson told SecurityWeek in an emailed statement. “The Microsoft Malware Protection Center actively supports third-party testers to use similar methodology in their test results. We reaffirm that Microsoft is committed to providing a trustworthy computing experience and continues to invest heavily in continuously improving our security and protection technologies.”
Four security products scored 6 out of 6 for Windows 7 protection: Bitdefender: Internet Security 2013, F-Secure: Internet Security 2012 & 2013, Trend Micro: Titanium Maximum Security 2013 and G Data: InternetSecurity 2013. Bitdefender was the only product to achieve 6 out of 6 for the repair metric which tests how well a product cleans and repairs a malware-infected computer.
