Yes. But it depends on what type of spyware is in question. Is the ports used by spyware a universal thing? No it is not. Most spyware use a dynamic UDP or TCP port.

If so, then couldn't I doubly safeguard the LAN (after trying to keep all the spyware off the workstations) by disallowing outbound communications via the firewall, for those ports? Or conversely, instead of allowing all outbound traffic, only allow the usual ports, such as 80, 443, 23, etc? Thanks. -- Matthew H.
