You may be wondering just what this is all about and whether you should be worried, aside from being so greatly annoyed by the software in question.

The real purpose of adware and reasons for concern

Programs of this type typically serve the purposed of the online marketing industry and with that said, there are a lot of different parties invested in them being distributed and carrying out their promotional activities. Such are, quite obviously, the different vendors and providers of the services and goods that are advertised by software like the one you are dealing with right now. On the other hand, the developers pf programs like “Cat.exe has stopped working” Virus are equally as vested in this process, because they, too, benefit from the promotion of the said products and services. In fact, more often than not, adware is involved in remuneration schemes like Pay Per Click that ensure the developers’ profit from the clicks made by users on the numerous popups, banners, box messages and various other ads. Therefore, the more times you click on the ads that are displayed on your screen, regardless of the websites you’re on, the more revenue the developers earn. It is for that very reason that the ads are usually so aggressive, but there’s more than just blatant aggression that programmers tend to rely on.

Because it’s in their best interest that you see and interact with as many ads as possible, adware programs can try to make their ads seem more appealing to you and therefore attract your attention. However, the means they often use to achieve this are generally frowned upon in the online community, even by security experts. What we are talking about is the ability of adware to monitor the affected users’ browsing patterns and record different information related to the websites you visit, the kind of content you share on social media and other platforms, as well as your most recent online search requests. Based on all this information, the adware can then adjust its ads and display those that are more relevant to the collected data, so as to appear more interesting to each individual user.

However, like it or not, this can be viewed as a privacy invasion and nobody wants be subjected to that. Unfortunately, though, that’s not all you have to worry about when it comes to programs like “Cat.exe has stopped working” Virus. Many people concern themselves with the question of its harmfulness and whether or not it’s actually a virus or some piece of malware. At least in that sense you can relax and be sure that your system is not infected with anything malicious. However, the numerous ads, for example, could potentially expose you to something of the sort, and we’re talking high-profile threats like ransomware and Trojan horse viruses. Hackers tend to inject their ads with malware and then wait for unsuspecting users to come along and click on the compromised ads and get infected. Therefore, we would advise our readers to try and avoid interacting with any of the ads, as there’s no way of telling the malicious ones apart from the genuine ones without finding out the hard way. It’s best to simply remove the program generating most of the ads, so as to avoid bumping into anything that may hurt you.
