Nobody likes Adware programs – once installed on a computer, a typical Adware would begin to spam the user’s Firefox, IE or Chrome browser with nagging and frustrating banners, ads, box-messages and pop-ups as long as it remains on the PC. Most of those programs do not have a disable option and will never stop nagging the user unless they are removed. The following few paragraphs will be focused on Kitty.dll “Virus” – a newly released Adware program. We will give you some important information regarding the potentially unwanted program and will also teach you how you can remove it from your PC if it has already gotten there. Note that it is oftentimes not enough to uninstall an Adware in order to remove it. That is why the removal guide that we will give you in this article contains a number of different steps that you will have to complete so as to ensure that Kitty.dll “Virus” gets fully removed. Also, know that we advise you to first read the article and only then go to the removal manual. When it comes to dealing with Adware, it is important that you are well acquainted with the different characteristics of this type of software.

Profit from Adware

The first important thing about Adware that we are going to address here is what these programs are actually used for and how their creators earn money through them. Obviously, a program such as Kitty.dll “Virus” is not going to be a paid product since no one would be willing to buy it. However, most Adware applications are still quite profitable for their creators. This is because they gain revenue through the adverts they display. The method that allows Adware to generate income is called Pay-Per-Click. With this technique, every click that a user makes on any of the ads is converted into a tiny amount of money. This might not seem remarkable, yet if Adware gets installed onto enough computers (and it usually does), the overall revenue earned can actually be quite significant.

Adware functionality

Many of you might be wondering whether or not there’s any actual use of an Adware program such as Kitty.dll “Virus”. Oftentimes it depends on the specific case and the program itself. There are many instances where a legit piece of software has a function that allows it to generate ads since this would enable the creators of the program to distribute it for free and still earn something out of it. However, there are also many Adware programs that have absolutely no actual use for the regular customer and are solely focused on spamming the browser with ads and thus generating revenue for its creators.

Security threat

Normally, even though Adware programs are commonly regarded as a form of malware, they are not all that dangerous for your machine’s security. Typical Adware will probably not try to harm your computer or mess with the data that’s stored on it. After all, programs of this type are mainly used for online marketing and as aggressive as their methods might be, Adware applications are still very different from actual viruses such as Spyware, Trojans, Ransomware, etc. Nonetheless, you must still remain cautious if you have Kitty.dll “Virus” on your computer, since it is possible that some of its ads might be hazardous. Many ad networks used by Adware developers have a shady reputation and are known to create ads that actually serve as redirect links to potentially harmful websites. If you want to keep your computer safe, it is best if you simply avoid interacting with any of the displayed banners, box messages, popups, etc.

Adware distribution methods

In order to prevent the installation of programs such as Kitty.dll “Virus” in the future, you’d need to know how they get inside people’s computers. Most users do not realize that they have landed Adware until the ads start appearing, since most of the time these programs get installed via different stealth installation methods. Some of the more common techniques for spreading applications such as Kitty.dll “Virus” are spam e-mails, shady Skype or Facebook messages that contain direct download links for the Adware, shady torrent or file-sharing sites that have a lot of ads and banners, fake Internet offers, etc. One other very successful and effective method for distributing Adware is the file-bundling technique. With this method, the unwanted application is combined with another program and gets installed along with it unless it is unchecked from the installation menu. Most users tend to rush through the setup wizard when installing new programs which is what makes file-bundling so effective. Our advice for you is to always pay close attention to what you are installing. If you see that there are added applications to the installer of a program, try to determine whether or not they are potentially unwanted and if you think that they indeed are, uncheck them before you start the installation process.
