Hi All,I have a Dell Dimension 3100C. I am being told by McAfee that my Windows Firewall appears to be switched off or disabled and to turn it back on. I don't remember turning it off and wouldn't know how to anyway. My question is how do I check if it is off and if needs be turn it back on. I use free edition of AVG 2011 if that makes any difference.Can anyone help please?

Contact McAfee Support and be sure to tell them that AVG Free 2011 is installed.~Robear Dyer (PA Bear) ~ MS MVP (IE, Mail, Security, Windows & Update Services) since 2002 ~ Disclaimer: MS MVPs neither represent nor work for Microsoft
