Definitely agree with Brandon. My own thoughts:

Whether to use antivirus on Windows is debatable. Steve Gibson of Security Now for example recommends against it and if it’s potentially a bad idea for Windows i’d highly question it’s use on Linux.

From what I understand conventional antivirus can drastically increase a system’s attack surface because of the amount of interpretative jobs it does and making matters worse it needs high privileges to run, so there’s lots of ways to attack it and if it’s compromised it’s holding the proverbial keys to the kingdom.

One of my favorite examples is when Norton Antivirus had a buffer overflow vulnerability in it’s email attachment scanner so if an attacker sent someone a malicious attachment it’d compromise their computer even if they never looked at their email, they just needed Norton installed.

I think there’s probably a place for antivirus in Linux but it’ll look nothing like the towering proprietary monoliths we’re used to and more like something that uses existing (and well maintained) software to spot anomalies and bad practices without increasing attack surface. Supply chain attacks are also a growing problem too which antivirus isn’t really designed for, at least not proactively.

Answering @CubicleNate or anyone else for SELinux, this starter video was HUGE for me and it’ll give you everything you need for basic problem solving.

# Option 1. Stream it in mono using mpv
mpv --audio-channels=mono 'https://www.youtube.com/watch?v=_WOKRaM-HI4'

# Option 2. Download and convert it to mono
