Spyware

Hello all:

I was just wondering if spyware sends its answers "back home" on any particular TCP or UDP 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.
