I run both Windows and linux. I’ve never had a problem while running linux. Has anyone found a problem with linux that Avast prevented? I’m using linux Mint, which is an Ubunto offshoot.
clear answer: purely on Linux itself: NO. But if you share NTFS partitions between Linux and Windows, or if you use USB flash keys, then, yes Because you could always without being aware of anything get malware on Linux, that won’t harm linux, but will leak into Windows. This said, even if it’s not the case currently, I’ve been dual-booting Windows with Linux a long time, and installed avast for Linux just once, and kept it very shortly, ie I just took the risk with no AV on Linux and nothing ever happened…but I don’t share NTFS partitions (NTFS-3G disabled), and I scan my USB keys when I’m back in Windows.
This all also depends on your browsing behavior.
It’s useful for an offline scan of infected windows volumes, for example. Also, some backdoors/rootkits etc. might be found on your system too. Interesting things can be found also in mail attachments, or inside the cache of your web browser :>.
