Yesterday morning I started my PC. I found that automatically was installed and started Avast Safezone Browser. It has installed itself without my consent. I have not downloaded, I have not give permission to installed, I have not asked for my pc to have Avast Safezone Browser.
I have uninstalled it, and done all my work.
Today morning I start my pc again, and guess what. It is installed again.
I know that I can uninstall it…
But it is not how it works. 
If I want on my PC the Avast Safezone Browser, than I will install it myself on my PC, but otherwise I do not want it on my pc.
I do not want to start every morning uninstalling Avast Safezone Browser.
What can I do?
How can I disable the Avast Safezone Browser auto install?
Thank you very much.
