Dear,

This is happening because it takes time to load all the signatures.
Using clamdscan instead clamscan will probably giving you sub-second scan because all the signatures are already loaded into memory and it's just waiting for a scan.

Why is this so slow? I see almost 100% cpu. But seriously on a 1MB file 2 mines? What could cause this high load? Can i speed this up a bit with kind of cache or something?

thank you! :)
