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.

FWIW, if you suspect your machine has been compromised, the binaries for common tools like
psandtopshouldn't be relied upon since those probably were tampered with to hide the malicious program from the output. At that point, you'd probably want to check each running process manually under/proc/.As of AV software I would like to point to ClamAV and Rkhunter.
Both should be available in most distro's package repository.
@RavenofDespair@lemmy.ml to add to this; you can use a firewall that's aware of what your systems is trying to contact. pfsense does this in their premium products and i've heard ubiquiti starting doing this as well.
