Help please!I don't think my Windows Firewall is working. When I click on the icon I get the message "Due to an unidentified problem, Windows cannot display Windows Firewall Settings".When I click on Security Centre I get a messsage it is not working and needs to be started. However, when I go in to services their is no option for Security Centre to choose so I am unable to manually start it or set it to Automatic.I use to run McAffee but having had my PC repaired the repairer installed AVG Free and MIcrosoft Security Essentials.I have been impressed by MSE so have cancelled my McAffee subscription and unistalled it together with AVG.I have also taken advice of Forum and used clean up tools on both McAffee and AVG.I am an XP user with the Media Centre version.Any ideas please as to what I can do? - I am not very tecky so simple advice please.Many thanks1 person got this answerI do too
