My phone got hacked/virus!!!!

I have reset all my settings, but should i sign out?? My phone recently got hacked because i went on a website "soap2day" and my phone kept getting notifications of " Your phone is gonna get virus this and that" and one of those notifications told me how to not get the virus on my phone and i clicked it and my Iphone said it was hacked!!! the website "soap2day" is a website to watch "free movies".
