I have an iPhone and just got a message says from Google that it has three virus's and I need to down load an app to fix it. Is this from Google or is it a hack?
That would pretty much definitely be somebody trying to con you into downloading an app which contains a virus onto your phone. As a general rule, ignore things that pop up in your browser and, if you're worried, download a reputable anti-virus software.
That's a scam. Google doesn't message you if you have viruses. That's done through an anti-virus program that you should download to ensure safe browsing.
The message from "Google" (it's not actually google) is a virus, itself.
