Key Coupons Adware

What is Key Coupons?

The Key Coupons rogue browser extension claims to save time and money by displaying special deals/discounts and enabling other useful features that will enhance the online shopping experience. This may seem legitimate and useful functionality, however, this add-on is categorized as a potentially unwanted program (PUP) or adware.

Key Coupons employs a deceptive free software marketing method called 'bundling' (stealth installation of additional programs together with other software) to install on Internet browsers without users' permission.

Following successful infiltration on Internet Explorer, Google Chrome, and Mozilla Firefox, the user will experience intrusive online advertisements (coupons, comparison shopping, search, etc.) that can lead to further computer infections.

Furthermore, Key Coupons continually monitors users' Internet browsing activity and records various software and hardware information including IP addresses, websites visited, pages viewed, search queries, etc. This collected data might be personally identifiable, and therefore, the behavior of this extension can lead to serious privacy issues or identity theft.

Key Coupons is similar (in some cases identical) to other rogue applications claiming to enable similar features. For instance, CoupSeek, AP Suggestor, Download Keeper, and SalePlus. All claim to save time and money by enabling identical features, however, as with Key Coupons, they provide no value to the user.

These applications are developed to generate revenue by the display of intrusive online advertisements and sharing collected data with third parties. For this reason, you are strongly advised to eliminate Key Coupons from your system immediately.

At time of research, popular freeware download websites such as softonic.com, soft32.com, download.com, and many others, employed small programs called 'download clients' (also called 'download managers', 'installers', etc.) to monetize their traffic and free services.

Download clients are developed to offer installation of promoted (according to the developers, '100% legitimate and virus-free') browser extensions or applications together with the chosen free software. Despite these statements, reckless download and installation of freeware often results in adware or malware infections.

This situation can be avoided by observing each step of the free software download procedure and never accepting offers to install additional apps. Furthermore, downloaded programs should be installed using the 'Custom' or 'Advanced' options - this will reveal any bundled apps listed for installation and allow you to decline them.
