My Windows Defender has found this trojan inside of the Immunet file system.  This happened yesterday and today on two different PCs.  Anyone else with this issue?  How should this issue be resolved?

Other anti-virus softwares can flag files of other anti-virus programs as viruses.
You can upload the file in question to virustotal (or use a SHA) to verify it

Hi JohnJ, if you create a custom exception rule for "Immunet's entire Program Files folder" with Defender that should stop the false positives from occurring. By default Defender is already excluded with Immunet.

If you're not sure how & you have Windows 10 here is a link that gives you detailed instructions on how to create an exception rule with Defender.

Windows 10's Defender automatically disables itself if it detects Immunet installed, so will only flag up Immunet's files if you set it to scan your hard disk regularly (which is off by default when you install another AV program). I haven't yet found a way of running the two in parallel like you could on previous versions of Windows.

Personally I'd just disable Defender completely and use something else as a second-opinion scanner for occasional on-demand scans, such as MalwareBytes, F-Secure Online, Emsisoft Emergency kit, or others...

All.  Thank you for the replies.  Since this only recently started, I'm guessing a recent Windows 10 update mush have re-enabled defender scans.  I'l prevent defender from making automatic scans.
