What is and why the wall of ads?

Like it is with more or less any kind of Browser Hijacker, was created with the sole purpose of generating tons upon tons of pop-ups, flashy banners, intrusive box messages and rage-inducing page redirects, which to top it all off – seem to be incredibly difficult to close. Apart from this, you might also have noticed a few other side effects, like a changed homepage in your browser or a different default search engine. Yes, these too are characteristics of the type of software you’re dealing with. Why all this madness? The root of it lies in the same place, where most madness stems from – money. The more ads the program displays, the more times they are likely to be clicked on and the more revenue this will generate for the developers of This is possible thanks to the Pay per click or PPC scheme, which is actually a pretty popular online money-making strategy. You’d be amazed how many businesses operate on this principle and in itself, there’s nothing wrong with it. The problems start, when people start exploiting it and try to squeeze out every penny from this oh so successful strategy.

The issues

First and foremost among the risks of having Browser Hijacker on your computer is the nature of some of the ads. Aside from being extremely invasive and obstructive, they can also prove dangerous sometimes. Though it’s very rare,some of the ads could potentially redirect you to malicious websites that are teeming with viruses of all sorts, including the infamous Trojans and ransomware. It’s beyond obvious that you wouldn’t want that on your PC. That being said, there is still a very clear distinction between Browser Hijacker and viruses. The two are not identical; they do not even remotely serve the same purpose and, furthermore, Browser Hijacker is most times considered completely legal.

The other issue, which most people think of as an invasion of their privacy, is the fact that programs like tend to spy a little bit on you. They can’t hack your online banking accounts or gather your passwords and see encrypted information, naturally, but they can and do keep track of your search queries, browsing history, favorite pages and other aspects to your surfing activities. If this doesn’t seem like a reason enough to be alarmed, you might want to think back on any personal details you may have left floating around on certain webpages that didn’t offer data encryption and a secure connection. That too will have been gathered by the program and the information can later be sold to third parties, of which neither you nor we have any idea.
