Unfortunately, even the most common and secure ones can be subject of this program’s infections: Firefox, Chrome and Explorer.

Generally speaking about Adware:

Adware as a term is used to describe the ad-displaying programs that are designed to produce ads in many forms while you are browsing the web. Some Adware-like software could also be able to cause some redirecting processes: your search requests to different web pages might actually send you to probably suspicious web sites. Because of all the possibilities above (especially the redirection) Adware could often be accepted as rather questionable. Some of its other sometimes intrusive features are its capability of collecting details about your search requests (of, course without your direct consent) and make the stream of the displayed pop-ups similar to the requests you have recently made. On the contrary, one program, which is malicious indeed, is likely to commit some really serious crimes: steal sensitive account credentials and use them; or even lock up some of your important data. In fact, “Cat.exe has stopped working” Virus is completely unlike any virus as it can never do such horrible things. This program is only capable of advertising products and services via its sometimes disturbing advertisements, but really of nothing more.

Is it possible to avoid programs like “Cat.exe has stopped working”?

Yes, and it is in fact easy. Maybe the first thing that comes to your mind is to stop downloading free software and stop going to suspicious web pages. In spite of that, it’s much easier said than done and we will let you know how to still use bundles and stay Adware free:

  • Then, when you have already downloaded a given bundle and you are ready to use it, just be particularly careful with the installation process you will perform.
  • When you see the installer opening in front of you go through all the menus there, read the End-User Agreement with great caution, and simply select a secure installation mode: the “Advanced”, the Customized”  or  the “Manual” one.
  • After that, simply select the needed programs from the list of the installed-to-be, and deselect the ones you will not need, won’t use or just the ones that look suspicious to you.
