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?
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?
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?
Please confirm if you are still facing the issue? If yes, I will send you an email to remote into your computer and have the issue resolved.
