Norton anti-virus and SSL

Norton AV (maybe only older versions, i.e., 2005 or less) is incompatible with security connections to email servers (SSL). When trying to access your server using SSL, you are blocked and Norton refers you to a site for a fix. One fix is to upgrade for $60. The other is to remove email AV scanning. However, we removed that aspect of the antiviral activity and the popup still comes up. Does anyone know of a workaround for this, or is the only cure another security suite or antiviral app?
