CouponEx Ads Removal Guide

Hi there. I accidentally downloaded CouponEx on my laptop yesterday and I have already uninstalled it from control panel. But today I found my profile has been receiving constant pop-up ads. They blocked portions of the screen making it difficult to use. I have tried the ad scan program and did a virus check but nothing worked. How do I stop them? Help please.

“CouponEx” Pop-up Ads/Adware Description:

CouponEx pop-up ads are mostly caused by adware, spyware, and other malicious and unwanted software that can appear themselves on most popular web browsers like IE, Firefox and Chrome without any knowledge and consent. This program claims it can offer you various coupons, deals and other commercial offers while you are shopping online on eBay or Amazon to help you save money. But it is just a trick to make inexperienced users download it so that the program designer can earn affiliate marketing money. Once CouponEx adware gets installed, it can modify your browser settings in order to display continuous advertisements on all of your web browsers. Those advertisements could be in all kinds of forms, such as pop-up, pop-under, in-text or banner ads and they will appear whenever you go to Internet and interrupt your browsing activities frequently. Not only are those advertisements annoying, but malicious as well. Even though they seems to be appealing and can help you purchase some particular goods at a better price rate, but it is very risky to click on CouponEx ads because it may redirect you to shady website that contain unknown malware and spyware or even lead to financial loss as a result.

Adware is everywhere on the Internet. If you are not careful enough, it will be easy for you to download CouponEx adware or other similar adware onto your machine. Adware can bring various ads for users because it is designed to promote products and it usually comes bundled with free programs like video player, music player or games, in an illegal way. In most cases, if you uninstall this adware, the ads will go away immediately and won’t bother you anymore. However, there are many people get trouble in removing CouponEx pop-up ads because even though you have uninstalled all the things related to this program, it still displays non-stoppable ads on your computer. In fact, this program will do nothing beneficial to you and it cannot provide you any available discount as it markets. Instead, it modifies browser settings and registry entries in the background and adds unwanted add-ons or extensions for you in order to generate more and more ads. We do not recommend users to click its ads in any circumstance, instead this adware should be removed manually as quickly as possible.

Manual removal becomes a technical process that you should only undertake if you have experience with the Windows registry and know how to view and delete system and program files in Windows.

CouponEx is listed as an adware and a PUP (potentially unwanted application) that you should not keep installed on your computer. Once inside, it could be used to collect your personal information, such as browsing history, search queries, top visited sites, IP address, email address or even your geographic location.
