Honestly, the idea of looking through logs was very foreign to me when I
started using linux. And Arch Linux was my first linux distro I actually
got to know. I think Arch is an excellent place to learn these skills.

Okay, so in regards to ClamAV, I encountered no errors [1] starting
clamd with the service file in the clamav package [2].

You should check your service file at
"/usr/lib/systemd/system/clamd.service" and make sure it matches the one
I uploaded to pastebin. If you can link a paste of your log at
"/var/log/clamav/clamd.log", that would help. 

Your journalctl log can be captured using:

        journalctl -xe | tail -n 500 | tee journal.log 
                        ^^^                  ^^^ 
                Takes last 500 lines.     Saves and prints output. 

Make sure to check these 500 lines that get printed to your terminal for
anything sensitive, like passwords.  NetworkManager doesn't show
passwords in the log, but it does show network SSIDs and connection
protocols, and other bits of information. There's probably more in there
than you would guess (there is in mine).

I had some kernel panic problems I couldn't diagnose with a much-used
MSI P67 motherboard. I'm pretty sure it was a motherboard issue, since
I'm using the same power supply, most of the same RAM, and the same
storage (different motherboard and CPU) and I haven't encountered any
more. If you decide to do a fresh install and you still get kernel
panics, I'd guess it's hardware related. Like a broken SATA port or a
loose connection.
