Why does my phone keep searching for unknown websites

[AC Question]

Every time I go to use my phone, it goes straight to the internet to search for unknown websites

Welcome to Android Central! Do you mean that it tries to bring up a website that doesn't exist? Or it brings up websites that are unknown to you? It sounds like there's some sort of adware that's been installed on your phone, probably alongside some other app you installed (often a game). Uninstall apps one by one until the behavior goes away.
