In order to successfully handle a potentially unwanted program such as Kokoko.dll “Virus”, you’d first need to have a good understanding of what It actually is. Here, we will give you all the essential information that you might need regarding Kokoko.dll “Virus” and other similar programs. After that, we will give you a number of useful guidelines to help you avoid getting such software installed onto your computer in the future. Finally, at the end of this article, you will also have the opportunity to learn how you can manually remove Kokoko.dll “Virus” from your machine. Note that a simple uninstallation is oftentimes not enough to fully get rid of the unpleasant program which is why, in our removal guide, we have implemented a number of different methods to ensure that there’s nothing left from the unwanted software once you’ve completed all of the steps.

What is Adware and what is it used for?

The most common complaints regarding Kokoko.dll “Virus” is that it invades the user’s Firefox, IE, Edge or Chrome browser and starts filling it with unpleasant ads, shady online banners, nagging pop-ups and sketchy box messages. This behavior is typical for programs that fall under the Adware category which is what we believe Kokoko.dll “Virus” is. An Adware program is normally created with the single purpose of profiting its developers through the so-called Pay-Per-Click scheme. Each time a user that has the Adware on their PC clicks on any of the ads created by the irritating program, the creators of the Adware gain a small amount of income. Usually, this type of unwanted applications get installed onto thousands of computers each day, which is why Adware programs are actually quite profitable.

Can Adware be useful?

There are, in fact, a lot of legitimate programs out there that can be quite helpful. However, in order to keep their products free, many developers resort to integrating an ad-generating element within their programs. This allows the creators of the said program to earn some money while still providing the user with a free application. However, the majority of Adware programs are not like that. Even if Adware is promoted as something useful and beneficial, the chances are that it is really just a program that generates nagging ads and doesn’t do much else so as to make it worth putting up with its intrusiveness. If you have Kokoko.dll “Virus” on your PC, then you may want to get rid of it ASAP since it does not benefit you in any way and just keeps spamming your screen with sketchy and irritating banners, pop-ups and box messages.

Can Adware be harmful?

On the flip side of the coin, there’s the question about how potentially hazardous this type of software can be. While many see Adware as a type of virus/malware, it is worth noting that programs like Kokoko.dll “Virus” aren’t all that harmful. After all, they are primarily used to earn money through ads and not attack your computer or mess with your personal files. However, even though you might not be dealing with some nasty Trojan horse or Ransomware virus, it is still preferable if you remain cautious around the Adware and remove it as soon as possible. The ads you see in your browser that are coming from the Adware might not be safe and it is generally advisable to avoid any interaction with them. Clicking on any of those adverts could expose your PC to actual online hazards, since it might redirect you to some potentially illegal and harmful website. From there, your computer might get infected by all sorts of dangerous programs like, for example the ones we mentioned earlier (Trojan horses, Ransomware).

Ways to protect your PC

Before we conclude this article and show you how to remove the unwanted software from your PC, there’s one last thing that we ought to address, namely, how you can ensure that no more such programs get installed on your computer.

  • If you want your machine to stay clean and safe, one important thing to take into consideration is what websites you visit while surfing the World Wide Web. Our advice for you is to avoid the ones that look suspicious and have a lot of sketchy ads integrated within their pages, since those are very likely to land you some undesirable program.
  • Another thing to keep in mind is that sometimes Adware gets distributed via spam e-mails or Facebook/Skype messages. If you receive a new message and it looks like it could be spam, do not interact with it.
  • Combining Adware with other programs (also known as file-bundling) is commonly used to get the former installed onto more computers. In order to avoid that, always make sure that you know exactly what you are about to install on your PC prior to clicking on the Install button. Never forget to carefully examine the setup menu and see if there’s any added software. If something’s been added and you think that it might be Adware, do not install the main program unless you have unchecked the bundled application.
