Configuration & Best Practices

The default settings for McAfee VirusScan Enterprise typically require additional configuration and tuning. All McAfee VirusScan Enterprise module features are enabled by default. To get acquainted with the software, review the documentation below:

Root Certificate Expiration

The McAfee product line uses TLS for secure communication. Two certificates validate McAfee TLS chains, including a primary expiring in 2038 and a secondary expiring on May 30, 2020. If either certificate, or both, are present in your environment, TLS will function correctly prior to May 30, 2020. After May 30, 2020, only the primary certificate will be valid. Out of an abundance of caution McAfee is informing customers of this impending event.

Generally, certificates are auto-updated through operation systems and customers will not be impacted. However, in environments where automatic management of root certificates is disabled and the primary certificate has not been manually deployed, customers will potentially be impacted. KB92937 provides information on how to verify and install the primary certificate.

Failure to have a valid certificate will cause product issues including reduced detection efficacy.

The primary certificate that needs to be validated is in a customer's environment as below:

Subject : CN=USERTrust RSA Certification Authority, O=The USERTRUST Network, L=Jersey City, S=New Jersey, C=US
Thumbprint : 2B8F1B57330DBBA2D07A6C51F70EE90DDAB9AD8E
Expiration : 2038-01-18
