This page aims to help you remove Narrow Setup. Our removal instructions work for Chrome, Firefox and Safari, as well as every version of Windows and MacOS.

Annoying online ads are all over the Internet and it’s nearly impossible to avoid them. They normally appear when you visit specific websites, but in some cases they may take over your Chrome, Explorer or Firefox browsers and fill them with nagging pop-ups, banners and aggressive promotional messages without leaving you any chance to remove them. Usually, the cause behind this ads invasion is special software known as adware. The adware typically appears as a normal extension to your browser and could easily integrate with any browsing program. It oftentimes promises to improve your online experience in one way or another, but instead of that, it actually starts to generate tons of pop-up ads and to trigger sudden page-redirects to random websites. This behavior could be very irritating and could prevent you from browsing the web in peace. On top of that, in some cases, the adware could be related to exposure to unreliable online ads or sketchy websites. Thus, its presence on the system could lead to close encounters with potential security hazards such as viruses, Ransomware, Spyware or Trojan horse infections. That’s why it is usually advisable to be careful if such software operates on your system. It’s also important to have a good understanding of the nature of such apps and the methods that could help you uninstall them.

Sadly, adware is a very common type of software and has many representatives, the purpose of which is to aggressively promote certain products, services of web pages on your screen and to generate pay-per-click profits for its developers. Narrow Setup is one recently reported adware-like application, which tends to mess with the users’ browsers and to force them to generate various aggressive ads. For this reason, in the paragraph below, we will tell you more about its specifics and will try to help you uninstall it. You will find a detailed removal guide which describes how to locate and carefully remove the annoying ad-generating application and we strongly recommend that you follow its instructions in case you want to permanently save yourself from the ads invasion.

Related security risks

An application such as Narrow Setup might not be the most useful and the most pleasant piece of software that you might have on your system. However, to your relief, it is not the most malicious either. The security researchers generally regard adware as relatively harmless type of software because it lacks the malicious code which most actual security threats have. Such software cannot steal personal data form you like a Trojan horse or encrypt your files like a Ransomware virus could. Even if you let it operate on your PC, the adware is very unlikely to initiate any action of crime or any illegal activity, which could damage the system. This fact, however, should not bring down your cautiousness because, in some cases, the danger may not come from the software itself but from its ads. An application such as Narrow Setup might not contain the harmful scripts of a virus but the pop-ups and the sponsored links it might redirect you to might not be as safe as they look like. The reason is, they are often generated randomly from different ad-supported platforms and no one actually controls their reliability. That’s why it is not excluded that various nasty infections might hide behind the attractive offers and the blinking banners that can get displayed on your screen with the help of such software. For this reason, you should try to avoid interaction with them as much as possible or simply eliminate their source by uninstalling it.

Distribution

Adware is a commonly encountered type of software, which gets employed by different online vendors, marketers and web-based businesses. This software helps its owners to promote their items directly on the users’ screen and to earn revenue from sponsored ads positioning or pay-per-click remuneration models. That’s why the developers try to distribute it as much as possible and often include it in program bundles with other software as well as in free download links, ads, spam messages, torrents, automatic installers and shareware or freeware platforms. Applications such as Narrow Setup could commonly be found as “recommended” or “bonus” installs added to different browser add-ons, optimization tools, free audio or video players and some software updates. That’s why, in order to avoid them, you should keep away from their most common sources and always pay attention to the settings of every new installation pack. If you don’t know whether a given software installer contains additional bundles, opt for the Advanced/Custom settings and carefully go through every checkmark that contains components which are optional.
