Windows update blocking LiveSafe

My Dell XPS has just installed the following updates:

2017-05 Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB4019472)

Windows Malicious Software Removal Tool for Windows 8, 8.1, 10 and Windows Server 2012, 2012 R2, 2016 x64 Edition - May 2017 (KB890830)

2017-05 Security Update for Adobe Flash Player for Windows 10 Version 1607 for x64-based Systems (KB4020821)

Security Update for Microsoft Word 2010 (KB3191843) 64-Bit Edition

Security Update for Microsoft Office 2010 (KB3118310) 64-Bit Edition

Security Update for Microsoft Office 2010 (KB3191899) 64-Bit Edition

and now my McAfee LiveSafe, which came with the laptop and is still valid, is being blocked by Windows 10 saying the published is unverified. I can't remove the publisher name from the unverified list as the remove button is greyed out. Incidentally a lot of other antivirus programs listed as unverified.

I've been in touch with McAfee and they remotely tried to fix the issue but said it's wasn't a McAfee software problem

I've been in touch with Dell and after much ado they did a system restore which temporarily resolved the issue until the windows updates were installed again.

I've posted in the Microsoft community and they say McAfee needs to be updated.

When I click on the properties of the file McUICnt.exe, then click on digital signatures, then click details it shows this message: A certificate was explicitly revoked by it's issuer.

I would be grateful for any assitance.

System Restore would only serve to start the whole thing over again, so no point in it.

I would contact Technical Support again and quote the session ID number to them and ask for escalation.

I have Windows 10 but am using beta software on it with no issues, so not sure why you are seeing this.

One thing to check, however.  Is your system clock accurate time, time-zone and date?

Re: Windows update blocking LiveSafe

Do you have any other Anti-Virus applications installed also? Try starting in Safe Mode and checking for updates.

I have both Windows 7/Windows 10 and I am not experiencing any issue either?

Re: Windows update blocking LiveSafe

I'm having exactly the same issue.  I'm unable to start McAfee, and found out that "A certificate was explicitly revoked by its issuer".  

Were you able to solve this issue?

Kind regards
