Can you explain that a little bit more. Why remove spyshelter firewall? Isn't spyshelter firewall better than Panda firewall?
The spyshelter firewall is not really a firewall in the normal sense of the word. You will still need a regular firewall. This is what Rubenking says about it in his review of Spyshelter in PCMAG:
"
Not Precisely a Firewall
You probably have an idea of what a firewall should do. SpyShelter's firewall component doesn't precisely match what you're thinking. It doesn't attempt to put your ports in stealth mode. It doesn't manage Internet and network permissions for the programs you run. And it doesn't actively prevent exploit attacks."
In short, it gives you lots of good protection, but you still need a regular firewall.
As for Panda firewall, it is a regular firewall, but I read that it does not stealth all ports. True, Kaspersky firewall doesn't stealth all ports either, by default, but Kaspersky is sophisticated enough to make up for it by applying rules.
I am not sure Panda is in the same league.
I personally would turn off Panda firewall, turn on Windows firewall, and keep running the Spyshelter firewall. That way you have good protection without conflicts.
