Scanning files when deleting

Why comodo cis is scanning files that are delete ? Its so sloooooow.

cis 5.5 , 7 x64
When i`m deleting huge number of files ( 10000 or more ) cis is scanning all the files, the deletion process is slow. Can i fix this by changing settings ?

Is your AV set to Stateful? When setting to Stateful is of no help I would suggest to temporarily disable the av when deleting a big batch of files.
