Although the PGP 10.1 Release Notes do not indicate a problem with the Norton Personal Firewall under the section of Personal Firewall Compatibility, the following is included in these Release Notes:

Symantec Norton AntiVirus 11.x through 12.x, Symantec Norton Internet Security 2005, Symantec
Norton Internet Security 2006
■ No special configuration required for MAPI email.
When using POP email, enable Auto-Protect and disable the Anti-Spam and Email Scanning options.
Auto-Protect, which is enabled by default, provides protection against viruses in email messages when
the message is opened.

Disable SSL/TLS in Server Settings in PGP Desktop or PGP Universal Satellite. (In PGP Desktop,
select the PGP Messaging Control Box and then choose Messaging > Edit Server Settings. For
SSL/TLS, select Do Not Attempt. In PGP Universal Satellite, on the Policies tab, select Ignore
SSL/TLS.) These versions of Norton AntiVirus prevent all mail clients from using SSL/TLS, regardless of
the use of PGP software.

Symantec Norton AntiVirus 9.x through 10.x, Symantec Norton Internet Security 2003, Symantec
Norton Internet Security 2004
■ Disable email scanning.
