Thank you for your interesting feedback. Did you activate all signatures
or just e.g. sanesecurity sigs? I read activating all signatures turns
clamav into an evil memory monster, while only activating sanesecurity
sigs catches most and doesn't need that much resources.

What about pyzor or razor integration? Do they help or just burn
