Just a FYI: This morning I went to open the excellent software Tixati (for which I've been happily using for many years now) on my Windows 10 20H2 (19042.804) and Windows Security forced the exe to be quarantined as a potentially unwanted app (https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?name=PUA%3aWin32%2fTixati&threatid=292810).   It took out the desktop shortcut, Program Files exe and the registry entries.  I've had to restore and allow the PUA to get it working again.  Not sure why Microsoft Defender AntiVirus as of 02-March-2021 marked Tixati as a PUA.

I have noticed this too, that it has been blocked and unfortunately it was somehow deleted while in quarantine by my anti-virus so I was forced to re-install. I find it strange, and I'm not sure if it's blocking other torrent clients or just Tixati. I've been using her for years and have had no problems until now. Are they just doing this for points with copyright interests or something? There is no inherent illegality to torrenting, I'd hope windows would not block an app simply for association like that. makes me wish we weren't stuck with an OS with so much control.

Me too, tried to reinstall Tixati but it came up with same error message

C:\users\me\appdata\roaming\microsoft\internet explorer\quick launch\user pinned\task...

Windows cannot access the specified device,path or file.  You may not have the appropiate permissions to access the item

OK

same thing just happened to me

I had this happen to me just now. Windows website has no information as to why this program is classed as PUP. Luckily windows defender only poped up with options to allow, delete or quarantine so I clicked allow and had no issues.

Same. Fixed it by going to Windows Security>Virus & Threat Protection>Protection History>This app has been blocked (Low)>Actions>Allow. But this was after I tried uninstalling and reinstalling so I lost all of my settings and transfer history.

Same here. Had to allow and reinstall it, there was no option to restore from Microsoft Defender.

Maybe it was just a definitions fluke, like they did to Chrome a long time ago? lol

Set-MpPreference -PUAProtection Disabled

you could always try linux. i hear they make versions that look a lot like windows.

is anyone getting this PUA problem with an older version of tixati (pre v281)?

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.

I felt it was always inevitable that I switch to linux. I'm downloading Ubuntu with KDE right now lol.
