Where does CoupExtension come from?

CoupExtension is part of a big group of adware applications that randomize their names upon the installation. Thus, we can tell that CoupExtension is simply another version of DownSave, AllCheapPrice, DealEXpress and a number of other adware. All of these programs are supposed to have official homepages, but they seldom do.

The official website for CoupExtension should be available at, but it does not work anymore. As a result, we can firmly say that the only method of CoupExtension distribution is bundled software downloads. It means that you download and install this program onto your computer together with a list of other unwanted applications. Open your Control Panel to check whether you have a group of apps installed on the very same day. Keep in mind, that CoupExteNSion, CoupExteNSion or COupExtensioNN is still the same CoupExtension application.

What does CoupExtension do?

This application behaves just like any other genuine adware application. First, it collects data on your web browsing habits to generate your online profile. With the data collected, it connects the dots and then displays commercial advertisements on various websites whenever you browse the Internet. CoupExtension ads are usually related to your online likes and preferences since this application has collected information on you.

Technically, CoupExtension ads are just a minor nuisance as long as you do not click on them. Users should stay away from unfamiliar commercial ads because they might be embedded with outgoing links to malware-related websites. The same applies to CoupExtension as well. It is not the adware’s intention to infect you with malware or steal your information, but there is nothing much this program can do if it gets exploited by cybercriminals.

How to remove CoupExtension?

Since the risk is rather big, you need to get rid of CoupExtension immediately. Luckily, this program has an entry on the list of installed programs, so you can easily uninstall it via Control panel. Do not forget to check Mozilla Firefox and Google Chrome browsers after manual removal (the extension might still be there). Eventually, run a full system scan with SpyHunter free scanner to be sure that you have terminated all the unwanted applications for good.
