Antivirus test labs says Qihoo 360 switched AV engine in copies submitted for testing

Chinese antivirus firm Qihoo 360 Technology today was censured by three major testing organizations for cheating on the evaluations.

The three antivirus testing labs — AV‐Comparatives, AV‐TEST and Virus Bulletin, of Austria, Germany and the U.K., respectively — stripped Qihoo of all awarded certifications and rankings for this year. They will also put in place controls to make sure that Qihoo or others cannot “game” the tests in the future. Qihoo denied the charges, saying they were “without merit.”
