Yeach that was my personal preference but the profliferation of streaming services each with their own exclusive shows made me sail the black seas once again, so i was wondering if there is something to scan downloaded files.
If its even possible in the first place to get a virus on Linux that way.
No judgement on what you're doing online. In your case, don't download untrusted files, stream where you can. For all users, whether on the black seas or not, you should as a matter of habit use uBlock Origin in your browser, turn on the filterlists for security, ads, annoyances in particular.
