Driver support not up-dating

I have been receiving the following message each time the AVG needs to up-drivers. This has been going approx. 3 months now. I am not impressed.

"The subject is not trusted for the specified action"

How can I repair this issue.

Hello Stephen,

I will check this for you.

We will work together to sort this issue.

Please share the screenshot of the error message you receive when you try to update drivers.
