What spreads the ads?

The product that usually strives to spread as many ads as possible is named Browser Hijacker after the terms advertisement and software. The Browser Hijacker-generated ads might come in various sizes, shapes and colors – as newly opened browser tabs, as glowing banners or as numerous pop-ups and pop-unders. Also, this type of software is capable of infected all famous browser programs – it doesn’t really matter whether you use Opera, Chrome, Explorer or Firefox, you might end up affected.

Where is Browser Hijacker usually found?

Such ad-producing programs can actually be found at various places online. It may come to you within a torrent. Another possibility to find it is inside a spam email or its attachments. You may have come across an infected hyperlink and clicked on it. The most famous tool for spreading Startgo123 is the practice called software bundling. When programmers create software bundles, they usually include in them a piece of software they have created that is given for free to the public. However, they still need to make money to sustain their business and they add an Browser Hijacker-type product to generate income from the displayed ads. The more ads you see, the more likely you are to notice a product you need or like and click on the ad. This is a regular marketing practice called PPC {Pay Per Click}.

If you need a given program from the software bundle but not the Browser Hijacker plug-ins inside it?

To make sure that you don’t incorporate any Browser Hijacker-like program from a software bundle, it is necessary that you be careful when completing the installation process.

Trojans are used for breaking into your system by finding a weakness in the OS or any other installed program. There are also viruses that steal money from your bank account, spy on you with your own webcam and copy account credentials. Some malicious programs are capable of crashing your entire machine.

Browser Hijacker NEVER does any of the mentioned above harmful activities. It simply makes many irritating ads pop up on your monitor while you are browsing the Internet. Of course, some of its typical activities could be regarded as somehow questionable. For example, in order to generate only ads relevant to your tastes, some Browser Hijacker-based software might research your surfing habits and determine what you may like or want to buy. Also, some Browser Hijacker may be capable of producing so many ads that they might make your entire system sluggish. Apart from that, Startgo123 and Browser Hijacker in general is NOT suspicious at all.
