What adware programs are really about and what to be aware of

“Cat.exe has stopped working” Virus and other programs like it usually tend to boil down to a single purpose, as the name of this software category would suggest: advertising. As such, their main goal is to integrate with your browser and start generating tons of popups, banners, box messages, in-text links and various other online ads to display on the user’s screens every time they decide to open their browsers and surf the web. The purpose is, of course, gaining exposure for the numerous websites, products and services that they promote with those ads, which is how their vendors essentially benefit from the whole practice. But on the other hand, the adware developers are also equally invested in it, as they earn revenue in accordance with remuneration models like the popular Pay Per Click scheme or PPC. This ensures that they can make a small profit every time a user clicks on a given popup or banner that their adware generates. That way, if you picture thousands or even hundreds of thousands of users getting infected, business it pretty much booming.

However, the above also results in very aggressive advertising approaches and ends in users being harasses by the numerous ads, as you may well have experienced already yourself. In addition, the adware developers can often resort to various tactics that hardly any of the affected users would approve of, and we don’t either. Programs like “Cat.exe has stopped working” Virus often have the capacity of tracking your browsing history with the intention of extracting certain information from it. Such are usually the websites you like to spend the most time on, as well as the things you search for online and the kind of content you tend to share on various social media platforms. Based on this data, the adware program can then determine which of its ads will be more likely to ‘speak’ to you and attract your attention. As a matter of fact, you may have already taken notice of this yourself. The longer you have adware on your PC, the more you will see how the ads start to oddly relate to your latest browsing activity.

Now, with all that in mind, there’s also one more thing that users ought to know when it comes to these programs. We already mentioned that “Cat.exe has stopped working” Virus is not malicious and has no intent to harm you or your computer. Nevertheless, these programs could potentially make your PC more vulnerable to viruses and other malware, thanks to changes they often initiate to your Registry, as well as due to the constant ad bombardment. It’s not very likely, but still possible that you may run into a malicious ad (known as a malvertisement) in the midst of other ads that just keep reappearing on your screen. These fake ads are online advertisements that look no different from the regular ones, but have been meddled with by hackers, who have injected them with their malicious scripts. The moment you click on an ad like that, you can instantaneously end up getting infected by some dreadful virus and there’s no telling the extent of harm it could cause. Therefore, we advise you to simply uninstall the program exposing you to so many ads and avoiding any interaction with the ads that you see online.
