I am trying to lend support using a remote connection to someone with a XP Home machine. They had MS One Care and Uniblue Registry Booster installed but were warned that the Windows Firewall was OFF. They also had a problem with the fake trojan virus. I have uninstalled One Care and Uniblue and removed the virus in Safe Mode. I installed Zone Alarm (free trial) so it now has a firewall. Eveything I have tried says the Windows Firewall is under Group Policy and cannot be started. I don't plan to buy Zone Alarm. How can I get control of the firewall when I uninstall ZA?
