I have just installed COMODO firewall pro and I have seen a MAJOR slow down in everything it takes forever to boot and just to open a application it takes forever. I gave it some time to learn the programs I normally use but it still is slow. It takes about 5 seconds for what I type to appear on screen also.

I'm running Windows XP Pro SP2, I have 3 gigs of RAM everything was working fine and fast before the installation. I have used Comodo in the past and never has it slowed down my PC.
