Avast slows down Farmplan Business Manager

I am running software" Farmplan Business Manager" and when I select the option “Internet Backup” it takes around 20 secs before the menu appears. If I disable Avast, it appears instantly. Farmplan have suggested some files which could cause the problem and I have put these into the Avast exception list, but the problem still occurs.
Is there any way I can get Avast to log which files it is checking, in order to try and sort this problem?
Thanks John
