The pop-up that is titled as ‘Visit Myrtle Beach‘ is actively related to some adware program currently installed and actively running on you PC. You can’t get this pop-up just by itself. It is definitely a part of the adware which is indeed active on your PC. For example, if you have the adware called Quicknowledge, you will see its Ads by Quicknowledge, which will display these visitmyrtlebeach.com pop-ups. However, when you try to click them, the chances are that you will be brought to some misleading or even dangerous websites, or to the websites of really poor reputation.
