On trying to update PortableApps.com_Platform from installed VERSION 30.0.4 Microsoft Defender Antivirus detects
PUATorrent:Win32/QBitTorrent,
see at https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-descri....
Both setup executables
* PortableApps.com_Platform_Setup_30.1.paf.exe
* PortableApps.com_Platform_Setup_30.1_UpdateFrom_30.0.2_OrLater_ONLY.paf.exe
are blocked on Download, so Installation / Upgrade is not possible.
Is this a false positive?
Or is PortableApps.com_Platform really infected/equipped with QBitTorrent feature?

Looks like this may have been a short term false positive. I'm not seeing it now.
Sometimes, the impossible can become possible, if you're awesome!
OK, i will give it some more tries
I'm experiencing the same with Microsoft Defender blocking the download attempted by the updater as well as a direct download of the latest version, per the recommendation in https://portableapps.com/supprt/platform#manualupdate. Download detected as being/containing QBitTorrent.
Initial attempt to download was around 8:20 AM GMT-4, 9/29/2025. Attempted multiple times at various times in various manors (different browsers, attempting (and failing) to tell MS Defender the file is fine and to just continue, etc.) up until around 9:30 AM. All downloads blocked.
System: Windows 11 Enterprise v24H2 (build 26100.4946)
Attempted manual downloads via latest version of Microsoft Edge and Google Chrome.
Reading through the comments, the false detection is possibly due to the Enterprise OS Version:
Mine is also Windows 11 Enterprise v24H2 (build 26100.4946)
where some antivirus settings are controlled by the Domain and out of my reach.
The Security intelligence version is 1.437.214.0 and virus definitions updated @ 30.09.2025
I've reported the issue to Microsoft with both files for Enterprise users

Great, thanks
Please try it again now. Microsoft confirmed there are no issues with either file.

Not able to update as the installer is detected as a 'potentially unwanted app' and removed.
same here - none of the downloads working - even cannot compare the hash..
It shows as clean in VirusTotal in everything including Defender: https://www.virustotal.com/gui/file/452d481bfa25a46bb1e5eb8f63a4c6557d6d...
I just updated from 30.0.4 to 30.1 without issue on a fully up to date install of Windows 11 with Security intelligence version 1.437.212.0 and virus definitions updated to 9/9/2025 8:12AM. Scanning with this version of Windows Security shows no issues with the 30.1 installer or the update package.
Please update your definitions to the latest version.

Thanks John, your report to Microsoft has fixed the false detection,
Now i could install the update smoothly, no more blocking due to flse positives.
Thanks
To late for me. I had the PortableApps platform on my work-pc. When the update appeared, I downloaded it (didn't want to install). But the false virusdetection was already automaticaly reported to the helpdesk and they ordered that I had to delete all things related to portableapps. I already said that it probably was a false detection, but alas, they didn't know portableapps and probably didn't want to know it either.
The same situation as before:
Probably can be fixed only with once again reporting this issue to Microsoft for Enterprise users
