windows Defender in windows 10 detects the program as a virus of PUA:Win32/Tixati

Not as virus, but as PUA (https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/criteria#potentially-unwanted-application-pua  )

PUAs are not considered malware.

Without consulting the user, it removes the program because Microsoft doesn't like it. How nice of them. Need to reinstall it now.

It Was Completly Removed In My Computer Now

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.

Here is more information:

You do not need to reinstall. Just go to Windows Defender Protection History > Look for the Apps Quarantined > Look for Tixati and select Restore in the Actions dropdown.

Windows will restore it as it was before. Have in mind that it will be re-quarantined every month or so when the Monthly scan happens. But following these steps should be enough to bring it back without any hazzle.

Cheers,
