Reports of Trojan Interjection using IWNet

The InfinityWard.com forums are receiving warnings from users that they are experiencing issues where they are having trojans interjected into their machine when joining certain IWNet games.

Users have been quick to point the figure that a clan has possibly hacked the game DLL files are injecting the trojans using a combination of those files and open ports on the guest clients end.

This issue is currently receiving mixed reports, we recommend strongly that you use antivirus (like AVG).
If you don't have an antivirus yet, you can download one legally for free at http://free.avg.com/ or at http://www.free-av.com/

MapModNews.com has reported that they believe this to be a false positive, http://www.mapmodnews.com/article.php/MW2-AVIRA-Crypt.XPACK.Gen-Trojan.

Update by KingOfTehInternets:
A ModernWarfail2.com reader sent me a screenshot of his Antivirus program (Avira) which picked up the Trojan:

Update by SlightlyGreen: I have people telling me it is a false positive so it might be. Because only Avira is detecting this, surprisingly.
