AdSkip may not be the proper solution in your fight against intrusive Web ads. The specialists describe this questionable application as a Potentially Unwanted Program (PUP). AdSkip may not achieve the job it is intended to do. In theory, AdSkip should serve as an ad-blocker. AdSkip is supposed to prevent the loading of video commercials and to stop distracting pop-ups and banners that you may encounter on various sites. The PUP blocks the ads that originate from viewed sites. However, AdSkip may place its own marketing elements in their place. The new ads may be far more aggressive that those that you saw beforehand. AdSkip may generate various commercial materials in addition to the pop-ups and banners. You also may detect large amounts of hyperlinked words or page-covering transitional ads. The function of this unwanted content is to transfer you to certain sponsored sites that belong to the partner network of AdSkip. The developers of this unreliable ad-blocker have financial incentives to redirect you there. It may be hard if not impossible for you to stay away from the promoted pages. The visible commercial materials that you can avoid are just one fraction of all ads. The others may be far more difficult for you to ignore. AdSkip may manipulate your searches by inserting sponsored links at the front positions. As you probably suspect, these ads don't have the typical slogan that can distinguish them from legit results. It is perceived as a bad idea to go to sites promoted by such applications. There is a serious security risk deriving from such activity. You may end up on threatening platforms that may try to infect your machine or collect information from you. AdSkip may change its offers and discounts to answer your current needs and wishes. This PUP may have access to all kinds of non-personally identifiable information regarding your surfing sessions, which may reveal your interests. It is not advisable to follow any ads no matter how appealing they may be. The proper response once you detect AdSkip is to delete it with special security software immediately.
