Moved to MWG for better handling
Hi, I have the same problem as jmazzeo07. What do you mean by: Moved to MWG for better handling?
well as the error states, this looks like an internal engine error with scanning the certificate file. You should open an SR with McAfee, and additionally you can temporarily whitelist the URL for antivirus scan bypass.
does this occur when scanning FTP traffic. There is a known issue at the Moment when scanning FTP traffic and GAM is configured to scan "unwanted programs".
Try to disable scanning of unwanted programs.
