What the subject says.  Did the 21h1 update to find Tixati missing.  Attempting to reinstall Windows Defender wouldn't let me.  Disabled Defender, re-installed, and all seems well with Defender reenabled.  Figured I should let everyone know.

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.

You must allow Tixati in the Windows Defender settings.

Strange. I'm on 21H1 too and I haven't had any issues with defender. I haven't changed too many settings.

Windows Security -> App & browser control -> Reputation-based protection settings -> Potentially unwanted app blocking (off)

Or add Tixati as an exclusion.
