I think my iPhone got a virus?

So I was in Chrome on my iPhone, then there was this weird pop-up saying something about me winning a prize because I was the 1000th visitor. So I closed the tab then I got the same pop-up again when I didn't click on anything and the site opened up again. I deleted Chrome, but I'm scared that I got some sort of virus…

Never say never but I seriously doubt it. First of all IOS is an really secure and locked down mobile platform. One aspect of that security is what is known as sand-boxing. Your browser, Chrome, was not running with root privileges on your device. Instead it was running a sandbox, so even if it somehow got infected by those annoying adverts the infection would be trapped in that sandbox and would not affect other applications or the OS itself.

Be more careful and educate yourself on good security habits.
