Can someone please help me figure out what this is. It looks like some ad pops on my website for no reason when opening website through google search results.
I've tried looking in code and couldn't find anything wrong. Hostgator also confirmed there is no malware on server and couldn't verify what this is. I have no idea how this got here in the first place and how to remove it.
If you click ok it takes you to [a] poker site.

It is quite possible that someone has hacked your website and placed an iframe or script in your pages. I have also faced the same issue. Some time it happens becaus of some add-ons installed in the browser, but if you are saying that you have checked at different systems, then browser does not have any issue and you need to look into your files and the hard thing is you need to do this manually.
