who knows ? but 12 scanners are currently showing the file as malicious and containing a specific trojan not just reporting 'random phone home' behaviour - which lots of software does.  The scanners that are flagging it are some of the biggest and most reliable scanners too. If they have submitted the file for a 'false positive' assessment as @Peter - IK Multimedia says then we should see it come up as clean.  This hasn't happened as yet.    IKM are not immune to viruses - nobody is.
