I am running Windows XP SP3, Malwarebytes Pro, Microsoft Security Essentials, and PrivateFirewall. When Windows starts it freezes. The keyboard and mouse do not work. I have to do a hard boot. I went into safe mode, disabled the PrivateFirewall, and now everything works. Everything was working fine until the last Malwarebytes update. There must be some conflict between Malwarebytes and certain firewalls. I am now using Windows XP firewall which works fine but is not a very good firewall. I want to go back to my other firewall. Please fix this issue.
