More like coupon-horrific, this nasty piece of malware is stubborn and difficult to remove.
Couponarific is an adware program that is commonly bundled with other free programs that you download off of the Internet.
Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed Couponarific without your knowledge. Couponarific is typically added when you install another free software that had bundled into their installation this adware program. Most commonly Couponarific is bundled within the installers from Cnet, Softonic or other similar custom third-party installers.
You should always pay attention when installing software because often, a software installer includes optional installs, such as this Couponarific adware. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place.
It goes without saying that you should not install software that you don’t trust.
