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..
I have recently reinstalled PC Firewall Plus (Free Edition) and now every time I boot up and the firewall program starts up I get the "Splash Screen".
I have never had that before and don't want it now. How can I get rid of it?
