Yesterday I discovered what may be a virus on my thumb drive. Or it could just be corrupted files, but I don't know which. Why do I think its a virus?
1) Whenever I mess with them (e. g. Attempting to copy or move them [which fails] or going in to the folder) causes my thumb drive to go into read-only mode.
2) Their combined file size is over 1 terabyte, although my thumb drive only holds 16 GB 3) Their are hidden folders that I can only see on Windows I found them in the files folder of a web page (two actually) that I saved to my computer. I could probably delete them, This virus(?) does not appear to be affecting Ubuntu.
