Norton Firewall found on Install, but is not installed

Hi,
I just started to install the new 3.18 comodo firewall and it gave me a message that it found Norton Firewall installed. I had previously uninstalled it a long time ago, but am worried since it says that the comodo might not work properly. I went ahead with the install anyway, but want to make sure it will work right or get advice on removing Norton more thoroughly.
Thanks
Kevin

Norton never uninstalls properly thats why they have a removal tool.

That’s the best cleaning program I’ve ever seen :smiley:
Notin’ left over (of Norton).

Welcome…have had to use it several times on customers pc’s I have repaired.
