I found the solution to let “simple interface” scan CAB’s also 
Go in “enchanged interface” > tasks > Local disks scanner > right mouse > edit task > you get a warning message, not to mess with default tasks > ignore it > go to advanced options ( tick little box in edit screen) >
now select “All unpackers”> press ok > now even in simple interface CAB’s are scanned.
so you don’t have to make a copy of the task, that you can only run in enchaged interface. Make note that a default task can’t be as modified as a copied one. But it solves the CAB’s and unpackers problem. And running a scanner without virus targetting doesn’t provide much more security anyway.
sweet.
