I'm presuming you're referring to PC Tool's "PC Firewall Plus". There are some similar named Firewalls.

I was unable to find a way of disabling. I did a search of PC Tool's Firewall Plus Forum, which yielded 9 pages of results/thread. I read through a couple of pages. Given the time, I might have found a post, which explains how to disable it.

If one of our members are unable to help, I would suggest looking at their forum. You may (or may not) find a way of disabling it.

Best of luck..
