Okay, I think I found the evil-doer, and it's, gladly, not related to clamav.
It appears there was an attack running towards one virtual host, which made the load skyrocket of the server - giving clamav only so much cpu time. It's still interesting that clamav showed up in top with 99% cpu: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 806 clamav 25 0 16560 16m 692 R 96.7 1.6 0:04.05 ls I will keep an eye on this, and post a follow-up if this problem persists.
