Guess it didn't like that I don't let them automatically update my system or use THEIR firewall. Really lame survey if you ask me. Didn't ask about any 3rd party security applications or if you use other methods to protect your PC.
In about 38 years of microcomputer use, I've gotten a virus once - when I got an infected floppy for a network printer driver. (The entire shipment of floppies to the network software company was infected.) So I think my "safety score" is about 100% by any real measure.
