The same here. And all my emails to McAfee are unanswered. We have this problem since two weeks, since we have change our emails system and the IP Range.
If you feel that the McAfee Global Threat Intelligence data is incorrect, and you are a McAfee customer, contact Support and have them investigate the issue. In many cases, Support can adjust the score directly. If you are not a McAfee customer, I would recommend emailing via the address above.
