johnsdp,
I usually leave my "module" settings at Normal. Avast has been very good at detecting "infections' using that level.
As for the scan function, I have my scanner set to Thorough with Archives. It is a bit slower and takes longer, but is a very complete way of checking the computer.
As for Eddy......Yes, he is always on top of things!
Nice to have you with us.
Welcome.
