Microsoft protested against the results on its official blog, calling them “unreliable” and defending its software as the most used in North America and other parts of the world.
“It is also difficult for independent anti-malware testing organizations to devise tests that are consistent with the real-world conditions that customers live in,” the company said.
“AV-Test shared some of the difficulties and shortfalls in many of the independent industry tests in a presentation they gave at the AVAR (Association of Anti-Virus Asia Researchers) Security Conference in 2012. We agree with them, it is difficult to get the tests right,” said Joe Blackbird, Microsoft’s malware protection center program manager.
AV-Test awarded another 22 lots of software with certification, with Trend Micro: Titanium Maximum Security 2013 and Bitdefender: Internet Security 2013 receiving the highest score of 6.0 score out of 6.0.
The two companies also joined Kaspersky Lab: Internet Security 13, and Symantec: Norton Internet Security 2013 with the highest score in repair garnering 5.5 out of 6.
On usability, Check Point: ZoneAlarm Free Antivirus + Firewall 10.2 & 11.0, ESET: Smart Security 5.2, Microsoft: Security Essentials 4.1 and Tencent: PC Manager 6.6 all scored 5.5 out of 6.
Of the 25 software evaluated only three, including AhnLab: V3 Internet Security 8.0 and PC Tools: Internet Security 2012, did not receive certification joining Microsoft’s MSE.
While denying MSE certification, AV-Test said products had to demonstrate their capabilities using all components and protection layers.
In the case of MSE, it scored a mere 1.5 out of 6 in protection, while PC Tools: Internet Security 2012 scored 1.0 out of 6 in repair and AhnLab: V3 Internet Security 8.0 scored poorly on all fronts.
