Free AV modifies browser, despite being told not to

After restarting Firefox today Avast popped up, telling me I had a “low reputation” search provider installed. I chose to keep the existing and clicked continue.

It then told me I had a low reputation browser add-on installed, namely “Download with DAP”. I chose “Skip”, rather than let it “fix” this “problem”, as I want to use this.

In the next screen I was told that my insecure search engine would be replaced. (!)

Without asking for permission my browser was then restarted and the add-on removed. My search engine remained.

I find this behaviour unacceptable. When I chose not to have my add-on removed then I don’t want it removed and I don’t want to have my browser restarted without asking, either.

Thank you for your time.

I haven’t had that problem, I don’t have the browser cleanup component installed, do you have it installed ?

Are you saying that this happened on restarting firefox rather than after say the Smart Scan ?
