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 :)
Windows defender is almost useless. It heavily relies on cloud for scanning. This is not a problem with special offline tools that some AV companies provide to disinfect systems that may not be able to connect to a network.
I recommend you check PC Security Channel to see how Defender works against ransomware when internet is turned off, versus on. You can also check performance of other AVs. He is the most reputed resource on benchmarking AVs if you want to see frequent updates, and a rare one that is not biased or rooted in nationalistic or weird biases, since he has his Patreon, Discord and a lack of dependence on lackeys.
Yeah I didn’t say it was perfect but does happen to be baked it
