Profit through ads

Obviously, Adware programs are all about creating and displaying various types of ads within the user’s browser. The people who create Adware earn money through the adverts that their products generate. Each time you click on a banner or a pop-up that comes from Cupduck “Virus”, a small amount of income is generated for the creator of the unpleasant program. This revenue-earning technique is normally known as Pay-Per-Click and it is basically one of the main reasons why Adware programs are getting created in the first place.

Is Adware useful?

When talking about Adware, one should bear in mind that there is a wide variety of programs that can fall under this category. Generally, any kind of software that is known to generate ads can be seen as Adware. However, not all Adware programs are the same. For example, some of them can actually be useful and beneficial for the user and the unpleasant ads are only there to support the developers of the program so that the software could remain free for use and still generate some income. However, there are also Adware programs that either provide the customer with no useful features whatsoever or the functionality that they provide is really limited and is not enough to compensate for the intrusiveness of the ads. Oftentimes, it is up to the individual to decide whether to keep an Adware program or to have it removed. We ought to mention, though, that some applications that fall under the Adware category can potentially expose one’s PC to certain security hazards, which is why it is generally advisable to remove Adware instead of allowing it to remain on the PC.

Is Adware dangerous?

The fact that Adware programs might sometimes make one’s PC more vulnerable is not to say that Cupduck “Virus” is some sort of malicious and harmful Ransomware virus or Trojan horse. Still, one should always be on their guard if they have some form of Adware on their computer. The one thing that you should be the most careful with is the ads generated by the potentially unwanted program. Some of those ads might be coming from shady marketing networks and could potentially cause redirects to websites with bad reputation or ones that might be illegal. Oftentimes, the banners and pop-ups that are created by Adware try to mislead the user into clicking on them. In some cases, there are even fake X buttons that, instead of closing the ad, actually redirect the user to some other webpage. Normally, you should not interact with anything that is coming from the Adware if you want to ensure the safety of your system and avoid landing any more unwanted software.

How did it get installed?

Most Adware programs use different methods generally referred to as stealth installation, in order to reach more users. Distribution methods for Adware include but are not limited to: spam e-mails, spam Facebook or Skype messages, deceitful and misleading browser ads, offers and even warnings, torrents, file-sharing sites, etc. One method that should be given extra attention due to its high success rate is the so-called software bundling. With this technique, the unwanted application is put within the installer of another program. In order to avoid installing the Adware along the main program, the user needs to carefully check the options within the setup menu, find the bundled application and uncheck it before launching the installation. However, many users tend to rush through the installation wizard and ignore the different options that are in it which is why file-bundling gets Cupduck “Virus” and other Adware installed onto so many computers.
