Originally assigned to: @VShawn on GitHub.

Malwarebytes flags PREMOTEM.EXE as a Trojan.Crypt in both the .7z archive and extracted.

To Reproduce

  1. Download latest release version from GitHub (https://github.com/VShawn/PRemoteM/releases/download/0.5.10.2/0.5.10.2.7z)
  2. Scan with Malwarebytes

Expected behavior
Files would pass MBAM scanning so as to not get automatically removed from the system.

  • OS: Microsoft Windows 10 Pro, 10.0.19042 Build 19042
  • PRemoteM Version 0.5.10.2

Hi thanks to reporting the issue. And I'm sorry that I am not a security engineer, so I don't know how to deal with such virus detection problems. Before anyone can help solve it, it is recommended that you include PRemoteM.exe into your virus detection whitelist, or maybe try the Microsoft store version.

I guess it may be because the exe version is not signed, and I added a registry entry for the software to start automatically, or wrote the registry for the Kitty configuration, which caused it to be detected as a virus.

Thanks for taking a look into it. I'm going to try add it to the white list on Malwarebytes. Having a signed exe would definitely be nice but I understand this is a lot of work. Also would it be possible to move the Kitty executable out of the main binary?

Yes its possible to have 2 variants - light without any dependency and full. On chocolatey at least you would then install it fully with cinst kitty premotem. It could also be added as automatic dependency which would require no explicit specification. PRM would need to support using kitty from the system (adding options in configuration to specify path if its not on the PATH, or if it is, just use it [as with chocolatey install]).

This obviously requires some work but release could be automated within #79 eventually.

I think this is not an option really.

Eventually I make some change by following this approach: https://stackoverflow.com/a/41272682/8629624

and It is no longer detected as a virus in GMail(still be blocked since it is .exe), Don't know if it will be detected as a virus by Malwarebytes.

I wouldn't be concerned at all, it is what it is. No other scanner detects it:

Thanks for all the work @majkinetor and @VShawn! I am going to add this to the Malwarebytes exception list and move on. I would like to take a look at a lite release when/if that happens and see if it still gets flagged. This ticket can be closed. Again thanks for your time!
