This is probably not the right community but I haven’t found a better one.

So I watched a video from Seytonic where he mentiond that some malware creates a windows link with the name of the usb on a usb. So I checked my usb because I remembered that I had to click 2 times on my usb to opened it. I found a link that contained cmd.exe and a name of a file next to it. Upload to the virustotal showed Raspberry Roblin worm.

I use Linux but my familly uses windows so I will have to go through all familly computers and remove the worm. Where can I find info how to remove this specific worm - Raspberry Roblin? On google I found a description about how the worm works but not specific files it creates and how to remove it.

The first page that shows up is microsoft.com and it says that windows defender detects the worm, but clearly it doesnt.

Edit: The worm was on one computer and it did not have windows defender installed. Seems like malware removed it and also disabled automatic updates. I installed MalwareBytes and sucessfully removed the worm :)

    Have you run a full scan using Windows Defender?

    Can you confirm that the worm is actually running?

    AV software may remove the installed worm from the system, but not from the drive.

    Probably a good idea to reformat the USB drive

    PS. if all else fails, nuke and pave (reinstall the computers in your household, including your linux machine)

    You should do this offline, as in, quarantine the situation.

      Windows defender also has an offline scan mode which may be of use here - hard to say, dunno if they ever dropped a rootkit or any other av-dodging/persistence mechanisms

        That would be a valid option, but only if there are no windows dependencies and the primary user agrees to the change.

        With all the Win11 spam in Win10, my grandmother decided to try Linux. She is now a 90-year-old Linux user. Her use case is YouTube and email, and I have to support the system (I had to do that for the win10 system as well).
