How to completely rid my iPhone 4S of avast virus protection?

I want to completely uninstall it, and so far all I've been able to do is turn off the VPN thing. I should have read the reviews before I installed it, however I did not. I can't use Instagram, Pandora, YouTube, Pinterest etc.

Try googling "iPhone hard reset". That might do the trick.

Scratch that it does not clear your apps sorry
