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

If you find this article useful and interesting, you could have been having some trouble related the appearance of some possibly unwanted and to some extent – too intensively popping-up ads. The aforementioned pop-ups and banners might be appearing on your monitor while you are browsing the web; whatever browser it is that you may be using. Even the most widely used ones such as Firefox, Chrome and Opera/Explorer may be displaying such ads. The possible reason for all of this is the contamination of your device with an Adware-based program called Kitty.exe “Virus”. In case this quick glimpse into the nature and effects of Adware is similar to what has been going on with your PC, your system has possibly got Kitty.exe “Virus”, and you may want to get rid of it. All the info we are going to share with you may indeed be what you need, especially if you want to find out more about this program and the software family it belongs to.

Adware and what to expect from it:

The alias ‘Adware’ is used to name all the ad-producing programs, which could be designed to broadcast ads in a variety of forms/shapes, while you are browsing the Internet. Some of the Adware-type products may also be capable of redirecting your searches to different webpages, or even to possibly suspicious places online, which have possibly been contaminated with threats worse than Adware itself. Because of the fact that such possibilities exist (especially the chance of being redirected), all Adware-based pieces could often be seen as suspicious to some extent. Some of its other somehow shady features are its ability to gather some info about your searches (without your knowledge) and fit the produced pop-ups to your usual requests.

Despite that, an ACTUAL malicious program is likely not just to review your tastes, but to illegally access private account credentials and use them; or even hijack some of your most important data. Completely unlike that, Kitty.exe “Virus” as normal Adware, can never achieve that. This program could only promote products and services via its pain-in-the-neck ads, however, nothing really worse can come out of that.

How may Adware access your device and infect your browsers?

In the next lines we would like to explain the possible manners, in which Kitty.exe “Virus” may use infiltrate your PC:

  • This ad-broadcasting software could get into your PC from a bundle, which contains freeware. Actually, this marketing trick is completely legal. Normally, such advertisement campaigns earn good profits for the people conducting them. That’s the reason why the programs which generate so many ads (or result in redirecting processes) are developed and distributed by web developers on a global scale.
  • Another typical way of distributing Adware is via putting it on various shady webpages. If you visit such a page unprotected, the result for you could be the stealth installation of Adware in your system.

Is it possible to stay away and not to catch irritating software like Kitty.exe “Virus”?

Of course, this could be achieved by staying away from the potential sources of such programs. However, these free bundles and web pages spreading Adware are often very tempting. Fortunately, there is a way to still use something from a bundle or freeware, and NOT get Adware from the inside of it as a bonus. The secret is to learn to install any piece of software you download in the most sensible way, which is described below:

We recommend that you go through all the available menus, read the End-User Agreements very carefully, and learn to habitually choose the “Advanced”, Customized” or “Manual” installation features, when you see a given program’s/ bundle’s installer. That is the way to always have the opportunity to select exactly what to install on your computer, and leave behind the unnecessary stuff.

One more helpful piece of advice includes ensuring that your pop-up blocker is enabled. This may not be able to prevent the Adware-spread ads. Nonetheless, such a program could be able to stop at least the web-page generated ones.
