This page aims to help you remove Kokoko.dll “Virus”. These Kokoko.dll “Virus” removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

The following article will revolve around a potentially unwanted program known as Kokoko.dll “Virus”. Due to the fact that this program has been reported to display intrusive banners, pup-up and box messages within the user’s browser, we believe that it can be categorized as Adware. Normally, it does not matter what browser is being used, since Adware programs work for most conventional browsers such as Chrome, IE, Edge and Firefox. Changing to another browser will likely not help either, since the Adware would probably get to it as well. The one truly effective way to prevent the ads from obstructing your regular browsing experiences is to simply remove the unpleasant piece of software from your machine. We will help you with that but first you need to learn more about Adware programs in general, so that you have a good idea about what you are actually dealing with.

How Kokoko.dll “Virus” profits its creator

Obviously, programs like this one aren’t paid since no one would be willing to spend money on software that usually has little to no actual use. In fact, most Adware applications get distributed via stealth installation techniques that allow them to get installed onto people’s computers without getting noticed at first. However, Adware programs are actually capable of earning substantial income for their creators. How do they do that? Well, there is a technique known as Pay-Per-Click, which basically generates small amounts of money for clicks that users make on the ads displayed by the Adware. With this in mind, it should now be more than obvious why applications like Kokoko.dll “Virus” tend to keep on creating more and more nagging browser ads. Of course, a single click on a single ad will result in a negligible amount of income, but one must keep in mind that each day thousands of PC’s get Adware installed on them. Usually, the overall profit from a single Adware program is quite sizable.

Can Adware harm your computer?

Something that users should keep in mind when dealing with programs the likes of Kokoko.dll “Virus” is that even thought they are usually not malicious and harmful, they might still be able to compromise the PC’s security and expose it to actual threats. Some experts and researchers tend to refer to Adware as a form of malware. Here, it should be noted that this does not mean Kokoko.dll “Virus” is some sort of a noxious Trojan horse or Ransomware virus. We already went over the primary purpose of Adware programs and explained to you what they are most commonly used for. Typical Adware is unlikely to try (or be able) to cause any substantial damage to your PC or mess with your personal data. However, as we already said, this is not to say that this type of software is perfectly safe.

The one thing that you ought to be most careful with if you have Adware on your PC are the various online ads that it generates and displays on your browser screen. Oftentimes, Adware developers use internet advertising networks that have a shady reputation. What this means is that you can never know if any of the banners, pop-ups or box messages you see aren’t actually redirect links to sketchy and potentially harmful websites that might land you some nasty Trojan or Ransomware virus. If you truly want to keep your computer safe, we advise you to keep away from those ads and see to the quick removal of the program that causes them to appear.

Stopping Adware before it gets on your computer

We believe that the best way to deal with a program like Kokoko.dll “Virus” is to simply make sure that it never gets installed on your machine. Sometimes, this might not be as easy as it sounds since Adware developers are known to employ various techniques that allow them to distribute their products and get them installed onto users’ PC’s without the latter’s knowledge or consent. Still, here we will give you a general idea what to be on the lookout for in order to prevent any more unwanted programs from getting installed on your system.

  • It should be quite evident that if one is to avoid Adware programs, they should stay away from websites that look suspicious and might not be trustworthy. It is not difficult to figure out whether a site is reliable or not – just make sure to stay from the ones that aren’t.
  • Something that is very commonly used for spreading unwanted software is spam e-mails or Facebook/Skype messages. Again, it is not overly challenging to discern whether a new message is spam as long as you are being careful and use your common sense.
  • Something that a lot of users tend to fall for is the so-called file-bundling. Many Adware applications get bundled with other programs and thus get installed along with them. This is why you must always stay vigilant when installing new software and never forget to check the installation menu for any bundled applications. If there’s anything added and you think that it could be Adware (or some other form of unwanted software) but still want the main program, simply uncheck the bundled install and then continue with the installation.
