Characteristics of adware programs
Initially, an adware app might appear to be no different from any other extension for a browser. Once installed, the adware would typically get added to the user’s default browsing program and operate from there. In many instances, the developers of the adware might even promote their product as useful and helpful addition to any browser and, truth be told, in some rare cases an adware piece of software might indeed hold certain beneficial features. In such a case, it’s up to the user’s judgement whether the app should be allowed to stay on the computer.

However, sadly, such instances are more or less an exception to the general rule which is that adware apps are mostly unwanted software components and it is typically better to have them removed sooner than later. Usually, the endless stream of ads and browser redirects are more than enough of a reason for the majority of users to quickly start seeking methods for uninstalling the pesky application from their browsers. In fact, it is likely that this is precisely how you have stumbled upon this article. One thing that still needs to be mentioned with regards to the adware family, though, is that most representatives of this software group aren’t malicious in themselves. Adware is primarily advertising-oriented and is hardly ever used to carry out anything harmful. Categorizing programs like Reaction Setup as viruses is technically incorrect as there are quite a few significant differences between adware apps/programs and malware viruses such as Trojan Horses, Rootkits, Spyware, Ransomware and so on. However, if you don’t want to land some nasty Ransomware or Trojan Horse virus, it is advisable that you do away with the adware that’s currently on your PC because of its uncontrolled stream of ads directed towards your browser. It is always a security risk to have random ads pop-up on your screen and clutter your browser because in many instances such ads tend to be used for malware distribution. Malvertising is, in fact, one of the top most popular methods used by all kinds of cyber criminals for spreading different forms of hazardous and harmful software. Therefore, once again, we advise you to get rid of Reaction Setup using our guide from this page or the recommended anti-malware tool that we have added to the said guide.
The installation of an adware program
There are indeed a number of ways one could get an adware installed on their computer. Clicking on some sketchy web ad or opening a spam e-mails attachment as well as visiting obscure and questionable web locations can all get your machine filled with carious undesirable apps the likes of Reaction Setup “Virus”. However, one other method for distribution of unwanted programs that many users ignore and overlook is the file-bundling. As you might know, the installers of a lot of programs offer you to also install some other “bonus” app or browser component on your PC. Such added components are actually very commonly adware or browser hijacker apps which is why it’s very important that you make sure to uncheck such optional installs when going through the setup wizard of a new program if they seem unreliable and potentially unwanted. Also, never forget to check the Advanced setup menu as this might be where the options related to the bundled apps might be hidden.
|Danger Level||Medium (nowhere near threats like Ransomware, but still a security risk)|
|Symptoms||Irritating ads all over your screen is the most typical symptom.|
|Distribution Method||Spam messages with shady content, software bundles, pirated downloads and so on.|
|Detection Tool||We generally recommend SpyHunter or a similar anti-malware program that is updated daily.|
