Ran an update and Microsoft Defender flagged DTaskManager as having a Trojan. I've quarantined the exe for the moment.
\PortableApps\DTaskManagerPortable\App\DTaskManager\DTaskManager.exe
Threat detected: Trojan:Win32/Azden.B!cl
Alert level: Severe
Date: 10/05/2020 12:05 PM
Category: Trojan
Details: This program is dangerous and executes commands from an attacker.
This is a false positive.
See here for the results of the antivirus scan of DTaskManager Portable.
When it comes to that specific file, I don't have an AV scan link handy for it, however you can upload it yourself to VirusTotal to check. As with our apps, note that there may be the odd false positive that is noted - a true positive will be identified by the majority of providers.
