How to remove CouponViewer

Have you mentioned aggressive pop-ups in the browser that come from the CouponViewer search engine? Have you noticed the name CouponViewer somewhere else on the PC? If any of these is true – your PC is infested with adware, and our article can assist you to get rid of it.


What is CouponViewer

CouponViewer, as you might have guessed erenow, is adware. CouponViewer can't do anything well, as it was developed to achieve only one goal: to drive you crazy. Surely, your annoyance isn’t its real task, but you'll be irritated anyway until CouponViewer does its job – distributes ads. It infects the laptop, it modifies the settings of your browser and displays you lots of links, ensuring that you click at least on a few of them. Hackers earn some tiny amount of money for each click you’ve made, and now you understand why the ads appear again and again: it’s a real bonanza. In the paragraphs below, we will explain in which way the virus got onto the computer and how it might be protected against suchlike viruses. In case you already know it all and simply want to delete the virus ASAP – skip the other sections and go to the deletion instructions.

Since the infection is performed, CouponViewer modifies the settings of your browser. It’s only thing that it can do, because the main part of this illegal system is the “search engine” which appears in the browser as soon as you download CouponViewer. So, the virus changes your default start page, as well as the pre-set search engine and places the scammer’s search in their place. Now you cannot use the reliable Yahoo, Google, Bing or any other search you're used to – you will browse the Web through the miserable fake search, displaying suspicious pages advertising banners pop-ups and other suchlike trash. Another adware's task is to spoil the properties of the shortcuts of your browsers so that even if you return the good settings, you'll see the scammers’ search engine in the starting tab.

If you've already bothered to delete this adware, you might have realized that it recovers, no matter how many times you deleted it. It happens because of the virus' protective mechanisms, and we can define their essence:

  • The most usual method of security is to develop a scheduled task for the restoration of CouponViewer if you've uninstalled it. Scheduled tasks are not typically utilized by usual PC users, so the adware simply creates a task to see if it is running, and if it isn't – to get and set it one more time. That task verifies the CouponViewer's status after each reboot, and that’s why CouponViewer keeps coming back.
  • The second manner has the similar aim, but it employs the system registry and not the Scheduled Tasks service. Fraudsters make a new string to system's registry and you have to detect and erase it, which might be difficult. The regular registry entries are crucially important, and by deleting one of them, you might inflict significant damage to the system.


How CouponViewer got into the system

To make easier for you, we’ll depict the process in total. 99% of the advertisement-oriented programs are copies of each other, repeated countless times and transferred to different scammers with minor changes made. Some evil lads purchased CouponViewer in the Dark Web, tuned it and published it on file-sharing services around the Internet. That’s where you found it, huh? Wait, you're saying that you haven't looked for adware that will irritate you? Maybe, you searched for a perfect spoiling-it-all-up program for your computer, and found a useful link to CouponViewer downloader? Still no? Well, in that case, you sought for another utility that is really helpful. Sort of a free software created by an unknown company, or a hacked version of some paid software you're not going to buy.

We know this method as the “bundled installation”, and its essence is that swindlers unite the installers of several viruses and one useful software to create one file. The main point of that bundle is that its name is the name of a useful software, and you can't know which tools are there before the installation starts. On some of the stages, you're allowed to see a proposal to get more utilities, with all checkmarks filled and the first desire is to get them and move on. And you pressed that button. Don't forget about another method, with the “ways of installation”. Usually, the installation for experienced customers is just a pick of where you need a program to be established, and how many additional programs do you need. In case of CouponViewer, if you clicked the offered method of installation, you allow all the viruses from the package into your device.
