For me, it was perhaps simple-scan, a very simple and efficient GUI to scan documents. I used it with my Brother printer / scanner and it works like a charm. Especially since I do not scan stuff often, so a program with more complex UI would have the effect that I forget how to use it until the next time.
But, why?
I don’t know, but my guess is it might still be able to detect some cross-platform malware signs and detect malware intended for Windows on Linux machines (e.g. I can download a PDF or .docx that is harmless on my machine, but if I reupload and a Windows user downloads it, I’ve spread malware regardless). IIRC ClamAV is sometimes used to scan attachments on an email server, often looking for Windows exploits being sent through the server.
That kinda makes sense
Reminds me of a ransomware problem that a place I worked at had. After weeks of computers getting reinfected over and over. It was figured out it was one “techy guy” with Linux on his work laptop. He kept sharing infected files.
So since he kept infecting the windows PCs on the network. It got Linux and macs banned at work.
Everyone had to have windows PCs moving forward.
Lot of Linux and Mac folk don’t realize how big of a vulnerability they can be even if they themselves aren’t affected.
