This is a fairly new FC5 installation, new ISP, and new wireless

appreciated.

rkhunter and possibly chkrootkit have not been modified to take into
account the FC5 norms (I think).
I scanned from "/" with f-prot yesterday and there were no
indications of "infection."
The point of a rootkit is that any command / program could no longer
be trusted: eg scanner asks OS: "open file x to check if its a got a
virus" OS responds with "data" - but it is not the real data inside
the file.
I've got the following installed:
rkhunter-1.2.8-3.fc5
chkrootkit-0.46a-2.2.fc5.rf
Is your chkrootkit the same version ?
It think it's worth installing rkhunter (either from core or extras -
I've forgotten) for a second opinion.

I did yum install this morning and "chkrootkit -V" shows "chkrootkit
version 0.46"
I'll try rkhunter as you suggest, if all else fails I guess I can
re-install but hate to wipe out my configuration effort to date.
Thanks. BobG
