How would you know?
If you are not running a virus scanner, how would you know if your infected? Do you think the virus writer will pop up a helpful window telling you? You expecting to see a process called, "virus.exe" or a dir called "malware".
Of course not. Today's malware is written to be stealthy. The biggest sources of new infections aren't file attached to emails, they are drive by downloads on web pages.
So not running a fw and not running av - not a good idea, not good advice to give others.
