nothing in which folder?

the whole point is that you need a folder below /run/ where your clamd 
stuff lives and that this folder needs to be writeable by the user clamd 
is supposed to drop it's privileges to

the folder and user depends on the packages of your distribution and 
"create a subfolder" is just to prevent a needed reboot since tmpfiles 
is only supposed to run at boot time

no idea how to explain systemd basics here, but your problems are not 
really clamav specific, it looks like you don't understand the current 
operating system version and it's tools at the moment and i fear here is 
not the place to put the pieces together

"I'm banging my head and previous upgrades didn't give me problems like 
this at all" for me sounds the upgrade path of your distribution or the 
package of your distribution is just broken and so create a bugreport 
there while in the meantime downgrade (if you can't downgrade your 
operating system management needs some re-thinking)
