Statement regarding Tencent products in recent Windows tests
After in-depth investigations, certain optimizations have been identified in Tencent products which are clearly designed to improve their ratings in AV-TEST's performance testing. These optimizations, which have been found in all recent public versions of the products, provide minimal benefit to normal users and could even degrade the level of protection offered by the products.
All three testing labs involved in these investigations - AV-TEST, AV-Comparatives and Virus Bulletin - expect participants in their tests to behave in an open and ethical manner at all times, and consider this sort of "gaming" of tests to be unhelpful to both developers and users. The labs will be imposing stricter controls on participants to reduce opportunities for such actions, and will revoke all affected certifications and awards granted so far in 2015.
