With a recent Windows update, my Transmission shortcut disappeared from Favourites. Opening it from the actual shortcut, I got an error message about Network Resources not being available (which I can't reproduce now that I've finally re-installed Transmission).
When I went to re-download the client installation file, Windows Defender kept deleting it, marking it as a virus. Finally by temporarily disabling "Reputation-based protection" including "SmartScreen for Microsoft Edge" (I use Chrome) and "Potentially unwanted app blocking," I was able to get into the Protection history and see that the download file had been quarantined, labelled as a "Severe" risk. I was able to restore the file from quarantine, run the installation again, and now Transmission seems to be working.
But, what happened exactly? I'm a little apprehensive that I had to temporarily disable anti-virus to get it working, and really hoping I haven't exposed myself to something unwanted.
PUA:Win32/TransmissionTorrent
Re: PUA:Win32/TransmissionTorrent
Seems something hit Microsoft in the head on March 2 and they added not only Transmission but also QBitTorrent and Deluge to the PUA (Potentially Unwanted Applications) list. Based on their own definition,
FYI uTorrent and BitTorrent are on that same list since February 6, 2017, and with a very good reason. Another entry was added for BitTorrent on March 2 as well. Needless to say, we aren't extremely excited to be in this not so good company; if you find a way to report this false-positive to Microsoft, please do.
This is most certainly a false-positive since none of the apps display any ads or install any additional (unwanted) software. As for computer (or most probably network) being slow, that's a reasonable expectation unless limits are set up.Potentially unwanted applications (PUA) are a category of software that can cause your machine to run slowly, display unexpected ads, or at worst, install other software which might be unexpected or unwanted.
