Hi @Christian11875 ,

What version of Windows?
Does the PICSimLab executable or installer have the problem? What version?
Which trojan is detected?
What antivirus do you use?
I have installed PICSimLab and run it on several Windows computers without this type of problem. I need as much information as possible to try to detect the problem.

I use Windows 11, Defender and the newest version of Picsimlab. An older version of Picsimlab and ALSO the Installer doesn't run. Last year both does run.

Dunno if a false positive or not, but had a similar thing.
Downloaded from SourceForge I believe, if my chrome download history is to be trusted (using link https://cytranet-dal.dl.sourceforge.net/project/picsim/v0.9.2/PICSimLab_0.9.2_241005_win64_setup.exe?viasf=1)
On Windows 10.
Windows Defender marked PICSimLab_0.9.2_241005_win64_setup.exe as Trojan:Win32/Wacatac.H!ml
I had also installed it and after scanning it, Windows defender marked picsim.dll as Trojan:Win64/CobaltStrike.BI!MTB

I had run MalwareBytes before a Windows Defender Full scan, but it didn't find anything

I updated my windows 11 and now the picsim.dll file is detected as a Trojan:Win64/CobaltStrike.BI!MTB! This detection is a false positive. I don't know how to proceed to solve the problem. Maybe recompile the picsim.dll library with other options?

I have contacted Microsoft about the false positive. I am waiting for their response. Only Microsoft Defender makes this detection, other antiviruses do not find any problem.
