Linux mint19.1There is antivirus for Linux, but it's usually not suggested since Linux usually isn't susceptible to viruses. You're likely to get several people replying telling you to not bother. Clamav is what is suggested if you really want AV on Linux. It should be available in your distros app repository. You can get it via the gui (possibly Synaptic) or by terminal with the command "sudo apt-get install clamav". I'm assuming by Linux 19.1, you mean Linux Mint 19.1. If I'm wrong and your distro doesn't use apt-get, replace that with the appropriate command.
