During the 1st quarter of 2011 we have tested 22 security products in the areas protection, repair and usability. The "Protection" covers static and dynamic malware detection, including real-world 0-Day attack testing. In case of "Repair", we check the system disinfection and rootkit removal in detail. The "Usability" testing includes the system slow-down caused by the tools and the number of false positives. A product has to reach at least 11 out of 18 possible points in order to receive a certification. 17 products have fulfilled our requirements and received an AV-Test certificate.
