I believe that this false positive problem is ongoing because today (January 18, 2017) I installed COMODO Internet Security Premium 10 (version 10.0.0.6092) with the latest virus signature files. Very shortly after installation it quarantined the Telerik.Windows.Documents.Core.dll file which is included with our corporate phone system software. COMODO Internet Security Premium 10 thinks (incorrectly) that the file contains malware "Backdoor.Win32.NetWiredRC.DS.@346199067"
FYI the version of Telerik.Windows.Documents.Core.dll we are using is 2015.1.0401.40
It's not hard to go to the Quarantine and also add the file to the "excluded files" list but it would be better if the program did not do a false positive on this file in the first place.
I submitted the Telerik.Windows.Documents.Core.dll file as a false positive.
