[clamav-users] Clamd memory usage running high?

[Reindl Harald]

the much better question is *why* is clamav that much memory wasting 
especially 385 MB for the official rules which barely hit anything and 
are removed here entirely from production machines for some weeks after 
hit nothing over the last 3 months - any catches was done by 
sanesecurity alone

that whole thing don't scale at all compared to any other AV solution 
which runs fine on a win7 virtual machine with a total of 2 GB RAM
