Please submit samples to the clamav team so the FPs can be resolved.

That sounds as if it may be generally useful.

Setting "PhishingScanURLs no" definitely works on my FreeBSD system. Note if you are using clamscan you need to use the "--no-phishing-scan-urls" command line option.

does the command
# clamconf | grep Phish
show the expected settings?

Does the command
# clamconf | grep conf
show the expected path names?

When you test some file manually with clamscan and/or clamdscan does it work as expected?

Unfortunately, clamd doesn't seem to log (all) options on startup, so the log isn't terribly useful this time. -- Noel Jones _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://lurker.clamav.net/list/clamav-users.html
