Un Install Security Products Carefully

If you decide to un install any personal firewall or security product, please be aware that many products may create components in the operating system itself, that are not easily removed by a simple un install wizard. Symantec and Zone Labs products (Norton and ZoneAlarm, respectively) are well known for this. If you have any antivirus or personal firewall product, and wish to un install it as part of a diagnostic procedure, please include these steps in your procedure:

1. Research un install procedures with the vendor of the product in question.
   
2. Enable firewall before un installing. Do not un install a firewall while it's disabled.
   
3. Carefully follow all instructions from the vendor.
   
4. Check for LSP / Winsock corruption after un installing, if any more problems are seen.
