NOTICE! We recognize that viruses change – they have different versions – so if something doesn’t work properly, or if the removal guide outright fails to solve your problem, do not hesitate to leave a comment and we will help you manually. Apart from the instructions below, the rest of this article is dedicated to helping you understand how Ads by CouponGiant and other viruses of its type operate. Since this is the most common kind of malware, we figured that we can help you avoid ever getting stuck in such a situation. To do that we will list all useful facts we could think of. First of all, it’s very important to understand that these things are designed to trick you. The reason they do it is because in all earnestness, they are are only a crude promotional tool that forces you to visit certain websites. However, since whoever creates them knows you will do everything you can to remove Ads by CouponGiant, they made a side-function to the virus – to manipulate you into installing more of its kind. That’s what we mean by tricks. These can be in the form of:


Fake banners around the pages that say you are missing plugins, and need to click there to install them…


Fake messages impersonating useful and legitimate programs and features like Java, Flash Player, Adobe Acrobat Reader, or even Windows itself. The messages will prompt you to install non-existing updates, and can be practically indiscernible from the real thing.


Imitations of universally acclaimed anti-virus programs like Kaspersky and Norton. The real danger here is that most users go on “autopilot” whenever their anti-virus program asks for something. They just accept to matter what. This is what the creators of Ads by CouponGiant are banking on, so know that any asks for permission to renew database or perform a system check-up are fake.


Redirects whenever you click on the advertisements – there’s a 30% chance this might occur. When it happens you will land on web pages that have nothing to do with the products you were viewing. Make sure to exit the at once – they contain malware much worse than what you’re dealing with right now – ransomware. The pages will start automatically downloading an installer in a matter of seconds; if this happens cancel the .exe immediately. If you fail to do this, a setup will autorun when it finishes. If THIS happens, open the task manager and stop the associated process. Trying to cancel from withing will result in nothing.

WARNING! Aside from these things, you should know that when Ads by CouponGiant was installed, it started tracking your browsing history, behavior, accounts and passwords. We recommend changing your passwords the moment you delete it from your system – especially ones connected to any credit cards.
