I have now switched to a Win7 64-bit machine and have NOD32 Biz AV for 64 bit installed on it. However, with Firefox 3.6.15, I am trying to log onto the Lufthansa site, www.milesandmore.com, where I have to log on with a username and password. I get this, after putting in the login information: Secure Connection Failed An error occurred during a connection to www.miles-and-more.com. You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. (Error code: sec_error_reused_issuer_and_serial) * The page you are trying to view can not be shown because the authenticity of the received data could not be verified. * Please contact the web site owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site. What is the problem here? It is obviously a SSL issue, where I have currently set NOD32 to: "Ask about non-visited sites (exclusions can be set)" And have the checkbox selected for: "Block encrypted communication utilizing the obsolete protocol SSS v2" Internet Explorer just simply doesn't show anything, blanks out.
