Oh yeap! It's either a bug or something is not working right! On mine, my homepage is google and i make changes to the avast online security settings in the google chrome browser. It stays fixed, but if i go to another new website the changes that i made in google it gets reset.
Before facing this issue. I save changes in the avast online security and click on settings on that and a new tab comes with with extra settings and functions. I then make changes according to my needs and save them. So from there on end, every site that i go to states that all the changes that i make is applied to every site. Now that's not the case.
Anyhow, I am still waiting for Avast support response on my support ticket.
