Soft tonic pop up...Please help

This pop up showed up on my Mac (late 2012) when my mom was using Google Chrome. It will not let me close the whole web page, but I am able to see the other web pages that were already open. Is this malware or a virus? Also, any ideas on how to get rid of it? Is it as simple as selecting "Prevent this from creating additional dialogue?" When I tried to close Chrome out completely, it was grayed out, and something new showed. It is the second picture and says "Warn before quitting $1."

Any help is greatly appreciated!
