Norton 360 Premier Blocking Thunderbird Email

Norton 360 Premier installed yesterday. Running Windows 7.

History log shows Norton is now blocking Mozilla Thunderbird email. History log shows Thunderbird blocked TCP on port 110 when I try to retrieve inbound messages. I am able to send email using Thunderbird.

Added to Thunderbird to firewall program list to “Allow” and still cannot connect although the “blocked” log entry is gone.
