Hi When I click on the folder for comodo firewall the following appears. C:\Program files 3\Comodo|Firewall|cpf.exe is not a valid Win 32 application. What do I do? Thanks.
It means it is not compatible with your operating system.
Could be you have xp 64 bit and this is for 32bit.
If you downloaded it ,go back to the site and choose a download to match your operating system.
