Tencent QQ – How Is It Spread

There may be several methods by which Tencent QQ may spread onto your computer. The program may be encountered as a bundled application in case you download applications from third-party websites. Such websites may be of the following character:

  • Torrent websites sharing software installers.
  • Randomly visited third-party software providing websites found online.
  • Websites that are advertised via adware on your computer.
  • Sites which are advertised on social media.
  • Programs that are shared in p2p sharing software such as DC++, for example.

Just when we thought the nightmare was over, we decided to check Internet Explorer, only to find out that Tencent QQ has modified Registry Entires to set its website qq(.)com as a home page:


The cherry on the cake was when we decided to use the search engine of the software, which redirected us via a new tab to a hoax search engine, called Sogou, which is known in the malware research world as a name copied by several browser hijackers, like the Sogou Browser Hijacker:
