The purpose of NetRatings is unclear. Symantec reports that it "tracks Internet usage and submits the tracked information to a server." and that Nielsen//Netratings is the vendor. PestPatrol states the same in their analysis.

On the other hand, McAfee alias for NetRatings is WebHancer and does not offer any information about the vendor.

Sophos' alias is Troj/Premete-A and does not offer any information about the vendor.

NetRatings is bundled or installed in association with file sharing programs such as Kazaa, Morpheus or Grokster.


Bundled software
