From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The xz issue might not directly affect an anti-virus, so maybe in this specific case, it would work fine. But it wouldn't be hard to come up with another library that would make the anti-virus moot. And even in the xz situation, doesn't it affect systemd?
All bets are off when you can no longer trust low level software like this.
Also, the Ken Thompson Hack comes to mind.
Didn't Guix solve that one with its full-source bootstrap?
Sorta.
You still need to trust a full Linux kernel and x86 hardware system.
I am not familiar with that. From a quick glance it looks like the new HURD. But I think even there you're relying on the work of others.
