I know that this is not a trojan. It is an addon for a steam game called Payday 2. I have seen several others with the same issue...
Refer to this post
Many scanners detect this as a trojan 14/51 scanners
If you feel you need to have it checked to see if the detection was false you will need to submit the file as per the link in my signature and post the analysis id number here. If no reply re the issue in 5 days post back and I will get a tech to personally check it.
