If a PC is infected by a virus, it is sometimes difficult to know or detect
with virus scanner because most virus can cloak themselves. But they usually
have some sort of LAN or internet traffic, either in an attempt to infect
other PCs on the LAN, or to download "payload update", or to send off stuff
collected (bank account info, ...).

So, is there a network monitor specifically designed to detect virus
activity on a home LAN that I can run on a dedicated PC?
