I need help! McAfee will not let me access a certain website that I need to access. Anyone know how to override the McAfee antivirus protection? I need to access a site on my community college website to do assignments! I have a Dell computer with Windows 10. I previously had problems off and on accessing the site, but now I cannot access it at all. I have been emailing tech support at the school for 3 days and nothing has helped. The error messages I get say there is a problem with the security certificate of the website.
