With NOD32 is not possible to access the site http://cmt.caixa.gov.br I have done various configurations, one of them was to add the site to the list of sites excluded from filtering. I added the address in "trusted sites" in Internet Explorer and to no avail. Always displays the message "Access to the certificate failed." I can only access after they turn off the antivirus. Through research I found two alternative links to access the site. Links: http://cmt.caixa.gov.br/nova/ or http://cmt.caixa.gov.br/cse With these links the access problem has been resolved in Windows XP. The problem is that Windows 7 does not work. Displays the same error message. "Access to the certificate failed." I do not know what else to configure. Have you seen something similar?
