This is a ClamAV (not amavis) issue.  The false positive is due to the 
anti-phishing signatures in ClamAV.  This is currently a hot topic on 
the clamav list.

You can disable the phishing heuristics in your /etc/clamd.conf file, 
which default to:

# With this option enabled ClamAV will try to detect phishing attempts 
by using
# signatures.
# Default: yes
#PhishingSignatures yes

# Scan URLs found in mails for phishing attempts using heuristics.
# Default: yes
#PhishingScanURLs yes

You can also soft-whitelist senders (if you are able to determine them) 
via @score_sender_maps in amavisd, and also have amavis map phishing 
pseudo-viruses into spam scores instead of treating them like viruses:

@virus_name_to_spam_score_maps =
   (new_RE( [ qr'^(Email|HTML)\.(Phishing|Spam|Scam[a-z0-9]?)\.'i => 6.0 ],
   ));

This will treat clamav's phishing hits as spam hits, boosting the score 
by 6.00 (set the values as you see fit).  See the amavisd.conf file and 
documentation.
