I don't know when this happened exactly, but I think it was after the last update for Clam that came out this week,
but the scanner is causing pretty high loads and scanning takes forever.
It isn't seriously affecting the server speed at the moment (it's a pretty powerful machine), but I would appreciate it if you could have a look at it.

I've asked the guy who installed the server for me if he had some advice.
he told me this:
it appears that Jamie isn't using the clamd (deamon) in Virtualmin pro, but lets each user start it's own clamscan, which is a bit inefficient, don't know where to change it though.
he says it would help if the command would be changed to clamdscan
hope this helps..
