Ads by Coupon Addon

What is Coupon Addon?

Coupon Addon is a potentially unwanted program (PUP) compatible with Internet Explorer, Google Chrome, and Mozilla Firefox. This browser extension claims to save time and money by displaying special deals and discounts when browsing shopping websites such as Amazon, Walmart, eBay, and so on.

Although this functionality may seem legitimate and useful, Coupon Addon is frequently referred as a virus or malware. These negative associations are made due to a deceptive software marketing method called 'bundling' employed by Coupon Addon to install on Internet browsers without users' consent.

Bundling allows developers to stealthily distribute their applications together with other software, and for this reason, most users inadvertently install Coupon Addon with other similar adware during download of free software from freeware download websites.

Today, most popular freeware download websites employ download programs (called 'installers', 'download managers', 'download clients', etc.) to monetize their free services and traffic. These small programs offer installation of advertised (according to the developers, '100% virus-free') browser plug-ins together with the chosen free software.

Thus, careless download and installation of freeware often results in adware or malware infections such as Coupon Addon.

Following successful infiltration on Internet browsers, Coupon Addon generates intrusive online ads alongside the promised coupons, and moreover, diminishes browser performance and tracks browsing activity by collecting various information that may be personally identifiable. Therefore, you are strongly advised to eliminate Coupon Addon from your Internet browsers.

There is a long list of rogue browser add-ons similar to Coupon Addon including, for example, PalMall, SmarterPower and TinyWallet. Rather than providing any real value for the user, these browser plug-ins behave in a dubious manner (delivering advertisements, tracking users' Internet browsing activity, etc.) in order to generate revenue.

To avoid installation of Coupon Addon, or other similar adware, pay close attention during the download of free software and click 'Decline' if installation of any additional programs is offered.

Furthermore, all software downloaded from the Internet should be installed using the 'Advanced' or 'Custom' installation options, rather than 'Quick' or 'Typical' - this will reveal any bundled applications listed for installation and allow you to opt-out.

PUPs such as Coupon Addon are listed within the Control Panel (Programs and Features) and in the list of installed extensions on Internet browsers (Internet Explorer, Google Chrome, and Mozilla Firefox).

If you have already installed Coupon Addon, and observe intrusive online advertisements while surfing the Internet, read the removal instructions provided to eliminate this adware from your Internet browsers.
