It looks scary, but it's only reading stuff that's stored in various places in your computer.
It gives me a very bad score because I have the machine set up for remote access when on my travels, and because I don't install every update that comes from Microsoft (especially the ones known to cause problems).
I rely on a good modem/router with good security (Draytek 2860), Avast antivirus (which catches several incoming virus-laden posts most days), and an instinct not to connect to any website with a red rating on WOT.
