Infostealer.Lemir.Gen is a generic detection for a group of Trojan horse programs that attempt to steal account information from the "Legend of Mir 2" online game and send it to the author of the Trojan.

The Trojan attempts to log details such as video game registration keys and online account information. In order to successfully achieve its primary function, the threat must run on a computer that contains the video game in question and is connected to a network.

This threat can often arrive by the following means:
  • File-sharing networks, as game enhancements
  • Online forum posts

If a Symantec antivirus product displays a detection alert for this threat, it means the computer is already protected and the Symantec product will effectively remove it from the computer.
