hello.

I mainly use Microsoft 365. The security program AVG informs me that one of the issuers of the certificate has expired.

The three issuers are listed below.

Microsoft Azure ECC TLS Issuing CA 01

Microsoft Azure ECC TLS Issuing CA 02

Microsoft Azure ECC TLS Issuing CA 06

I have checked the certificate at the link [https://learn.microsoft.com/en-kr/azure/security/fundamentals/azure-ca-details?tabs=root-and-subordinate-cas-list] to check related information. When I looked, the expiration date was marked as today.

How do I renew the certificate date?

It is in the default state because no special settings are touched while using the program.

    This seems more of a problem with Avast. All the issues here are with Avas. Is anyone not using Avast getting this error?

    We are getting it on some machines - not all. All are using Avast.

    Just got word from Microsoft support - They have advised the following

    "It is indeed a global concern affecting both Microsoft and Avast users. Our teams are actively monitoring the situation, and we appreciate your patience.

    Avast has already released an update to address this issue. To stay informed about the progress, you have a couple of options:

     

    1. Contact Avast Support: You can reach out to Avast’s support team directly. They will provide you with the most up-to-date information and guide you through any necessary steps.

     

            2. Automated Update: Alternatively, you can wait for the automated update. Our developers are diligently working to resolve the issue, and  we anticipate that the fix will be rolled out soon."

    It seems like its up to microsoft to fix, so we just have to wait it out.
