i have use the add/remove program to uninstall it and have deleted the trace by the regedit, but the window security center is still detecting it as (pc tools firewall plus is currently ON)
Sounds like you’ve still got some traces left behind in your registry.
Go to the site below and scroll down the page til you come to Free Registry Cleaners.
Click on EasyCleaner and download.
After it’s installed, run it and it should pick up any remians of your firewall.
