Using Tixati for years.  First time this has happened.  What's up?  How to get around this?  Should I get around it?

Tixati has NO spyware or adware.

It has been flagged as PUA (Potentially Unwanted Application) by Microsoft's Windows Defender only because Tixati is a torrent client. Other torrent clients have also been flagged as PUA by Microsoft's Windows Defender just for being torrent clients.
