qmail-scanner-2.02st log

hi list,
i have an QMS-2.02st installed together with clamav+SA. the log down here is showing 
something happening as far as i know, every morning at this very same time. could you do 
point me to on where i should look into for to have this sorted out - or is this running 
in normal behavior - if it is - what is this saying?
