Hi ellanios82,
How often do you update your signature database? How often do you do a scan?
Did this slowdown just occur in the last few days, or last couple weeks?
I am curious if the slowdown occurred after daily-25380.cdiff (a database
change that I am told removed many hash signatures from the database which
would be detected by more efficient signatures), or if some change to bytecode
signatures is causing much slower scans. The message you reported "LibClamAV
Warning: Bytecode 3 failed to run: Error during bytecode execution" isn't
necessarily due to a bytecode timeout (which is more common), but indicates
some sort of problem with a bytecode signature. If you can identify what files
cause this error, it would very helpful if we could analyze those files with
the signature to see what is going wrong.
Thanks,
Micah

p.s.
Omitted to say, 7 times i receive this message :

have expected 4 Hours to scan my 44 GB ]
thanks
