*** If the virus scanner is unable to update, then this is a good indication their update link (URL) is being blocked or redirected. Try setting your DNS server (network adapter setting) to 8.8.8.8 and try again. ... If the link is being redirected, it can be done thought the system 'Host' file or a DLL file.
