I upgraded from 4.8 to 5.0 and now it won’t run and I get this message. Anyone know what it means and how I can turn Avast back on?

Hi wirejock, welcome to the forum 
Is your Windows up to date ??? Updating Windows with all the updates/patches can solve this problem according to the forum members who had this problem.
Greetz, Red.
It was, but after I installed 5.0 now my windows updater won’t work either. I contacted Microsoft for that one too. Windows Updater gives me a 80070424 error.
