Anti-virus plugin for Iplanet 4.1

I need to know if there exists any anti-virus plugin foriplanet web server V 4.1 service pack 11 for solaris 8.

My primary requirement is that all HTTP/FTP traffic passing in and out of the webserver needs to be scanned for the virus if any. If it can be implemented in any other way Please let me know.
