Probably the following comment has nothing to do with your problem, but several frequent forum members here would suggest to get rid of IO bit’s tools.

To be clear, I don’t use them and I personally have no opinion at all. I’m just telling you what several other users here would suggest, independently of your current problem.

Please do NOT get this as a personal recommendation from my part, as I don’t have any experience of their tools. Certainly this comment has no relation to Avast Software in ANY way, as I am just a simple user as you are.

Possibly, you may want to solve this avast not updating issue first, before getting into an additional “project” (of changing things in your system).
