MS Update blocked by Avast
« on: January 23, 2019, 05:41:26 PM »
Just been having fun with uninstalling and hiding a problematic Office 2010 update.

I found I could not open MS Update Website whilst Avast shields were active. See attached. Seems to be reporting a Certificate issue.

I had no problem using MS Update website once avast shields were turned off (temporarily). I was then able to do the job I wanted to do there, i.e. hiding the offending update from being offered again in future.

You could set Avast to "Ask", so you've the final word.

@Asyn,
Fair comment.
I will see if Microsoft do anything about the certificate.

Some good news to share.
After some searching I think I have found a solution, unrelated to Avast.
This involved fixing microsoft update, by running MicrosoftFixit50202.msi tool on the affected XP machine.
I can now access update.microsoft.com on that machine without Avast returning a Revoked Certificate error and blocking access to the website. 
NB: That tool is no longer available or supported by Microsoft, but I had a copy of it in archive.
