>Description:
	I have tried to install clamav 0.66 and while it does run, it is
very slow and puts a high demand on the CPU.
Scanning one file with around 600 lines of text takes about 50 seconds with almost 100% CPU load (appr 500MHz Via C3 which is not fast though not more than 50 times slower than the P4 quoted below). 


time clamscan -v /tmp/CLAM  
/tmp/CLAM: OK

On a linux system (1.5Ghz P4) <1 second is the time usual for small files.


Is there anything I can do to track the cause of this?
