This page aims to help you remove PUA Coupon Viewer. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

If a program called PUA Coupon Viewer has been recently disturbing you with numerous ads, pop-ups banners, and intrusive notifications, then stay on this page to learn how to remove it. This program is a typical representative of the Adware group. Its main functions are related to the intrusive generation of various commercials, the aim of which is to make you click and purchase certain sponsored products or services. You may also often find yourself redirected to some websites, which may not be familiar to you. Their nagging popping notifications may constantly interrupt you, without giving you a chance to close them down. What may really irritate you is the ability of the Adware to take over your browser (be it Chrome, Firefox, Explorer, etc.) and install its ad-generating components without your approval and without giving you an option to easily uninstall them in case you feel overloaded with advertisements. This is the reason why many people consider software like PUA Coupon Viewer a virus and desperately look for ways to have it removed. Fortunately, adware is not a malicious infection such as Trojan horse or Ransomware, but if your browsing is disturbed, we will give you a detailed removal guide which can help you safely eliminate it from your PC.

Can PUA Coupon Viewer be harmful in any way?

As we just mentioned, Adware programs are not as harmful as a typical virus infection. In fact, they have no malicious scripts and do not aim to cause harm to your system. Unlike threats like Trojans, Ransomware, Spyware and the other types of viruses, which can definitely have devastating effects on your PC, a piece like PUA Coupon Viewer is a mere irritation. This adware basically serves as an online advertising tool, which aggressively tries to promote certain goods, services, web pages, or anything else, that needs advertising. What makes such software irritating is the amount of ads, banners and pop-up messages that it may generate and the way these ads may interfere with your normal browsing. It is surely not a pleasant web experience to get constantly interrupted by blinking boxes, links, and commercials, but still, a lot of marketers believe that this is the way to promote their items and make you purchase them. In fact, they pay fat amounts of money to have their ads exposed and clicked on as much as possible and the software developers naturally come up with tools like PUA Coupon Viewer that do the job.

For many users, however, such aggressive tools for ad exposure could be a real source of unnecessary web disturbance and irritation. Some people may even report certain negative consequences of having adware on their system. For instance, their browser may become sluggish due to the enormous amount of ads it may be forced to display. It is not uncommon for the browser to even crash, or redirect the web searches to some sponsored sites. Such activity may not only be irritating but may also land the users on unfamiliar or insecure web locations. Another quite invasive activity, typical for the adware applications is their ability to collect browser-related data and transmit it to some third parties. Usually, these are marketers and advertisers, who want to learn more about your recent searches and interests in order to offer you their products. In some cases, this may be a useful service, but in others, it may only lead to unnecessary exposure to spam.

 What could you do in order to effectively remove the ads from your browser?

To remove the ads from your Chrome, Firefox, or any other affected browser, you should uninstall their source. Fortunately, adware programs like PUA Coupon Viewer are not that difficult to uninstall. You can do that on your own if you follow a detailed removal guide, (like the one available below) or scan your PC with a professional malware removal tool.

The prevention of such software is a bit trickier. For this, you have to have an idea of how adware gets installed in your system. Usually, this happens thanks to a software setup (called a “bundle”), which contains a set of different applications, browser tools, games, system optimization tools, adware, etc. Most of these bundles are distributed for free through spam messages, email attachments, free download links, ads, shareware or freeware sites and prompt the users to install them in a “Quick” or “Automatic” mode. Our advice is to generally avoid such setup bundles, or if you need to install their main software, simply select the “Advanced/ Manual/ User” option instead of the automatic one. This will give you full control over all the bundled programs and will let you deselect the ones you don’t want.
