FYI – I use Avast Internet Security, which has a Chrome Extension that blocks these types of Google Ads and other similar pop ups by default, which is basically the same functionality that you would get by using the AdBlock/AdBlock Plus Extension for Chrome. Just thought I would mention that factoid. The Avast Extension can be turned On/Off for testing.
