From your image it looks like your File System Shield is set to Ask (which I have mine at also).
If you set it to Auto, the alert window allows you to select the Option to Report as a False Positive, this may be something worth trying as it should also transmit general information on the detection.
I think part of the issue is that it is svchost.exe launching this file and there are many instances of malware using svchost.exe (a legit windows file, services host) to launch other malware. So I think that this generic signature (the -gen in the name) is too aggressive in this case.
That is probably why when scanned in isolation (not launched by the svchost.exe) nothing is found.
