Differences from Windows to Linux for viruses: On Linux it is harder for the virus to get root (or system) level access.
If you want you can have it do regular full system scans too.
It is all about how paranoid you are, and how likely you are to get a virus.
For your laptop I would suggest only having the scanner scan downloads and when you are brining files from another computer.
Having it do full system scans can be a battery drain.
