Tencent, Qihoo antimalware firms are accused of cheating, stripped of rankings in antivirus tests

Chinese vendors Tencent and Qihoo have been accused of gaming antimalware tests by releasing optimized versions of their products for testing purposes that wouldn’t be reflected in the real world, several antimalware firms said. 

Both companies will be stripped of their rankings, AV‐Comparatives, AV-TEST and Virus Bulletin said. The three stripped the rankings of Qihoo last week, and of Tencent on Monday night.

Both Tencent and Qihoo finished among the top six antimalware vendors in AV-Test results released in March, which ranked the firms on protection, the performance of the engines, and how usable they were. But they will apparently no longer appear on the official list, just as a college basketball team can be retroactively stripped of their victories and individual awards if improprieties are involved.
