None, if no services are exposed. On W9x/ME systems, this is pretty easy. On NT
type systems, some (like RPC) can't be closed, or are not closed by default,
like Windows Messenger. For many users, using a firewall is easier than fiddling
with services. Then there is the matter of logging traffic.

A software firewall is also useful for controlling outbound requests, like
blocking HTTP requests from OE.

IMHO, Stealth is silly, as is "leaktest" signature checking. Stealth is silly
for the reasons already cited and signature checking because it really serves no
purpose. I have never heard of a trojan that replaces a known app, and trojans
that piggyback on known apps are never checked.
