Support Start > Disabling Norton Security Products

We've noticed that our customers frequently report connection problems caused by Norton security software, particularly when sending or receiving email.

If you use Norton security products and you have email, FTP or secure website connection problems, we recommend that you temporarily disable the Norton software as a test to see if it's causing the trouble. (Be aware that disabling the software temporarily lowers your security protection; you should re-enable the software after the test.)

Unfortunately, there are many different "Norton" security products, each of which has a different method to use to temporarily disable the program. Here are instructions for some of the more common programs:

• Norton AntiVirus for Windows, or Norton Virus Protection
• Norton Internet Security, Norton Personal Firewall, Norton Online Protection, or Norton Personal Firewall Online

If your program is not on the list, you should consult the documentation that came with the program to learn how to disable it.

Norton AntiVirus for Windows, or Norton Virus Protection

If you have email problems while using Norton Antivirus 2003 through 2006, first try temporarily disabling email scanning. See Symantec's page explaining how to temporarily disable email scanning.

If that doesn't help, or if you have other connection issues (such as problems with FTP connections), the Norton AntiVirus "Internet Worm Protection" feature (which is really a firewall) may be blocking the connections. This page explains how to temporarily turn off Internet Worm Protection (follow the instructions in step 3).

If either of these help, then Norton AntiVirus is causing the problem. You should contact Symantec (Norton) for assistance.

Norton Internet Security, Norton Personal Firewall, Norton Online Protection, or Norton Personal Firewall Online

If you use Norton Internet Security and have email problems, first try temporarily disabling email scanning. See Symantec's page explaining how to temporarily disable email scanning. (Follow the instructions to disable email scanning.)

If that doesn't help, or if you have other connection issues (such as problems with FTP connections), there may be a problem with the firewall portion of Norton Internet Security. This page explains how to temporarily disable the program completely.

If either of these help, then Norton Internet Security is causing the problem. You should contact Symantec (Norton) for assistance.
