Adware viruses are the most numerous viruses in existence and Ads by Coupon Giant belongs to the Adware family. It is characterize by a large amount of unwanted advertisements that pop every time you open a new page in your browser or start it. It is also possible for the virus to convert random words in any text you read into hyperlinks. On rare occasion it has been also known to temper with your default search engine or install suspicious toolbar.

Before we proceed with the removal, however, we have to discuss the virus in some detail.  This is important, because all kinds of viruses use similar methods to get into your computer. We’ll be talking about Ads by Coupon Giant in particular, but remember that the same tricks could be used by any other virus in existence.

A non-exhaustive list of commonly used methods

The first trick is actually very popular with Adware viruses in particular. It involved the so called program bundles. These are installers for programs, which can install more then one program when they are ran. The additional programs are usually supposed to be demos or trials of other programs created by the developer or his partners. Unfortunately in some cases inside could be hiding an Adware. The chance is much higher if you are dealing with an installer for a free program. All of this is a very good reason to always skip the default installation option and try the advanced one. It gives both knowledge AND control over what exactly will be installed and you can remove the access for all extras you don’t really need.

Another fairly common method are the Adwares themselves. Whenever any Ad offers you a file to download there is a very high chance that the file will be contaminated by a virus. In fact this methods is very common with the more dangerous viruses like Ransomwares and Trojans. This is one of the main reasons why you should never click on the Ads and download anything directly offered or through a hyperlinked site.

There are also the torrent and storage sites on the internet. All such sites are potentially very dangerous. First you will usually be presented with a multitude of “download” buttons and no more then one of them will be real. If you select one of the fakes then you will be offered with a download windows. The file offered might carry the name of the file you requested in the search query, but the file extension will be .exe and what is inside will be a virus.

One golden rule

Virus file will almost always be contained withing executable files. That’s why downloading such files from random locations is unwise. If you want to have something installed on your computer the proper course of action is to search for the official site on google and grab the file from there. That’s how you can be completely sure the .exe file you received is virus free.
