Better option I can suggest on this case is to contact McAfee consumer support so that you can solve the problem over the Phone with one of the customer support executive.
Please call 1-866-622-3911 and contact McAfee customer service to resolve this issue.
This solution works with me. I initially contacted McAfee team to fix it over the phone. It only last up to 20 minutes and everything has been working properly eversince. Thanks.
