Might be a fairly generic question. Clamav is very slow when compared to
most competion, for instance f-prot. Scanning a 15mg file same machine, same
file, and pretty much the same load, simple .exe, basic options:

Three tests each, worse times for f-prot and avgscan, BEST times for
clamscan and clamdscan:

F-prot

real    0m2.534s
user    0m1.460s
sys     0m0.330s

Clamscan

real    0m22.302s
user    0m18.970s
sys     0m0.570s

Clamdscan

real    0m4.690s
user    0m2.290s
sys     0m0.260s

Avgscan

real    0m4.690s
user    0m2.290s
sys     0m0.260s

Now granted, not likely to scan 15mg email attachments but I also scan ftp
and http downloads and cannot use clam for either because if someone
downloads a 50mg file it takes forever, f-prot is still measured in seconds.
