A couple of weeks ago I purchased Trend Micro Internet Security 2008 which has a firewall. Today a box popped up stating that a particular item (I forgot what it was) was being blocked by "Windows Firewall". It's my understanding that only one firewall should be installed. If that is so, how do I get rid the the Windows Firewall? I can't seem to locate it in "add or remove programs" or anywhere else. Any suggestions?
