How do I get rid of the browser add-on?

[system]

I really hate the Avast browser add-on.

It causes certain pages to become unresponsive in Internet Explorer and doesn’t even work properly in Firefox.

I know I can disable it but would like to fully uninstall it from my system.

How can I do this without uninstalling Avast?

Go to control panel >add/remove or Programs and features
Select Avast
On the left select change
Deselect “browser protection”
Follow the prompts

[system]

Thanks
