Do I have a virus on my computer?

[Ben Miller]

So on google chrome when you open a new tab it shows you your new tab page with like your most visited sites and stuff but now when i open it its just blank and when i click on a chat box like on facebook its highlited blue. i re installed chrome and i ran a malwarebytes scan and "no maliciou software was found" i dont know what to do. the blue hughlited thing also happens on internet explorer and i dont have mozilla
