My firewall is logging unusual activity.

Ad-Free • 18 October 2004

This article refers to a product no longer developed by ContentWatch.

Ad Free performs real-time blocking within your Internet session and may cause some firewall software products to log activity you haven't seen before.

For example you may see items such as "TCP Data has changed" false alarms.

Most firewalls allow you to 'ignore' this and other similar messages. Please refer to your firewall user documentation for information.
