Your best bet would to be to close the window and not interact with it at all. Pop-ups can be a tremendous annoyance, but there are ways to deal with them. While they do not function maliciously, these pop-ups can be just as annoying. Some online businesses use them as marketing tools to display visitor response forms and licensing agreement terms. Though very rare, some legitimate companies will deploy what they term as desirable or useful pop-ups on their site. These fake pop-ups should be treated with extreme caution as they can eventually become much more than an annoyance. The simulated pop-up and the page behind it are actually part of a full-screen advertisement hosting a spyware trap. This is a very confusing scheme that tries to lure users into clicking malicious content. Instead, there is a graphic within it that appears to be another pop-up window. In this instance, the entire page displayed within the browser window contains no content and is not a real page at all. You might also encounter similar windows that are not actually pop-ups. These are traps that display warnings in the form of security alerts, hoping you will click the window and download undesirable content on your system. A pop-up could also be a malicious program in disguise such as a Trojan horse. Sometimes the advertisements are highly offensive or even worse, adult oriented. More often than not, these busy windows exclusively display ads for content the user has no interest in. There are three primary types of pop-ups: those that appear when clicking something on a web page, those that appear at random, and those that appear without user intervention, the most aggravating variation. However, when you consider the level of annoyance they present, pop-ups and pop-unders are essentially one in the same. While they are generated by the same type of programming, some consider them totally different as pop-unders do not appear to b as intrusive. There are also programs known as pop-unders, which display windows behind your web browser window.
