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 :)
Syncthing and LocalSend.
Syncthing is used if it is not a one time transfer. LocalSend is mainly for one time transfer. LocalSend needs things to be in the same network. The same WiFi router is enough. Syncthing can send files over the internet also.
There are browser based alternatives like ShareDrop . These tools are not as reliable as Syncthing and LocalSend, especially when it comes to single large files (more than a few GBs), like ISOs.
For one time transfer over the internet, another handy tool is Croc . This one also suffers from the large file related issues.
