If you are seeking a way to terminate a program called Ad by Browser Extension and ensure that it never comes back, you should definitely read this article. This unwanted piece of software might not be the greatest problem that you can encounter online, yet it is still something most users would not want on their computers. This program is capable of displaying various intrusive pop-up adverts and banners on both your Firefox and Chrome browser. These are only some of the undesirable features of this annoying piece of software, but they are enough reason for you to want it gone from your machine.

Introducing you to Adware

Ad by Browser Extension is an application of the Adware type. This kind of programs is all over the internet and usually serves one single purpose – to gain profit for its creators. The technique that Adware employs so as to generate revenue is called Pay-Per-Click. This scheme allows the intrusive software to earn small amounts of money for each click on any of the intrusive pop-ups. This might not seem like much, but keep in mind that each day a huge number of computers gets infected by the Adware and even if a small part of their users click on some of the ads, the total amount of income is quite significant. This is also the reason why those ads you see do their best to be as obstructive and nagging as possible – this is just another strategy employed to make you click on those pop-ups.

Is Ad by Browser Extension harmful to your system?

When it comes to Adware, one of the most frequently asked questions is “is it a virus?” Well, fortunately for you, programs such as Ad by Browser Extension do not fall under that category. Instead, they are categorized as potentially unwanted programs or PUP for short. PUP’s, while most of the time being a pain in the neck without any useful functionality, are still relatively harmless to the computer they are on. On the other hand, actual viruses such as Ransomware and Trojans are definitely a major security risk that can devastate your PC and/or files. Therefore, it is not correct to refer to Ad by Browser Extension and other Adware programs as viruses. There is a huge difference between malicious Ransomware that can lock your data and require you to pay a ransom and a mere annoyance such as Ad by Browser Extension.

We advise you to be cautious around Adware

With all that said, it is still inadvisable to treat Adware applications carelessly, as if they were regular programs. In some instances, the ads you see popping up in your browser might hold security hazards. Thus, it is a bad idea to click on any of them. Of course, dangerous ads are rare, yet the chance of an advert redirecting you to some suspicious and shady webpage must not be underestimated. Apart from that, a lot of Adware programs tend to look through a user’s browsing history and search queries. This privacy invasion is done with the purpose to enable the Adware to display advertising materials that would be better suited to the specific user’s preferences. This in turn increases the chance of those ads getting clicked. However, no one likes to have their online activity monitored and this is one more reason why Adware programs should be removed as soon as possible and for this purpose you can use our removal guide below. On top of that, Adware could display overstated or outright false warnings on the computer screen that urge the user to buy some obscure PC optimization tool, which in most cases turns out to be nothing but another useless PUP.

It is easy to keep Adware programs away from your system

In most cases, an Adware program cannot get on your PC if you did not let it. Sure, users rarely realize how they have installed the unwanted software, but this does not mean that it has gotten there without them having done anything. This is because Adware developers like to employ different strategies in order to get their products inside people’s computers without them being aware of that. A general term used to describe such strategies is stealth installation and it normally includes distribution methods such as spam e-mails, illegal torrent files and deceptive links that directly download the PUP on your PC. However, it is the perfectly legal file bundling method that gets the most Adware programs installed. If Ad by Browser Extension is bundled within the installer of some other program, it gets installed along it if the user goes for the Quick installation option (which they usually do). This is the mistake that gets the Adware installed and in order to avoid it, from now on you have to make sure that you always use the custom installation setting. This one would allow you to leave any added content out by unchecking it before moving on to the actual installation. Therefore, the next time you are about to install some new piece of software, remember this tip and make sure that no unwanted applications get inside your system.
