I am having problem accessing some websites. I get a message the site certificate is invalid and advises not to access the site. Is this a security problem with my Internet Explorer settings? If so how do I fix it?1 person needs an answerI do too

Open Internet Explorer (only) to http://windowsupdate.microsoft.com | Select CUSTOM and scan | Install any Critical Security Updates offered (e.g., KB2183461). If a Root Certificates update is listed (possibly in the Optional Software updates category on the left-hand side of the scan results window), install it to take full advantage of IE's enhanced security.~Robear Dyer (PA Bear) ~ MS MVP (IE, Mail, Security, Windows & Update Services) since 2002 ~ Disclaimer: MS MVPs neither represent nor work for Microsoft
