Hi,
After the update of Avast free 2016 to 2017 version on my Windows 7 Pro, the Action Center alert me that Windows Update was desabled, but is not in fact. Windows Update is steel "green".
I don't want to desactive the message, that not a solution.
Finally, I used a system image of my computer to go back to Avast free 2016 and every things is ok now. I will keep this version until you fix this bug.
A link to the 2016 offline version installer will be apprecied.
Have a good day.
PS : I hate this kind of captcha as a lot of users!
