Recently I learned we can get a virus running DOSBox despite its area of action is limited to the files and directories I gave access through the mount command.
Wine and Proton aren’t emulations like DOSBox and “translates Windows API calls into POSIX calls on-the-fly”. In other words, it runs the DOS/Windows programs more directly to the Linux Kernel than DOSbox.
Then I wonder, can we also get a virus on Wine or Proton and is it more dangerous for the Linux system than the case of DOSBox?
