For the most part, a Browser Hijacker is an annoyance to the majority of PC users. The etymology of the name consists of the words advertisement and software. Simply explained, they are pieces of software supported by ads. Regardless of their seemingly harmless nature, they can become increasingly dangerous in the palms of malicious individuals – hackers, for example. Obviously, covering the development cost of a piece of software can be achieved using Browser Hijackers. This can allow the developers to issue free software. Bundles of software typically contain these ad supported software which a user installs on his machine. Another useful benefit of ads in this circumstance is the fact that legitimate software can be supported by motivating the developers to continue maintaining and updating it.
Despite that, it is important to note that not every single Browser Hijacker is harmless in nature. A handful of them are developed by profit hungry individuals who only aim to gain money from you. They supply the software with ads that display in a myriad of ways – all of them being annoying and / or obstructive. As a whole, they worsen your overall computing experience and can harm your productivity. Malicious Browser Hijackers possess the cunning ability to install themselves into your computer without your consent or knowledge, but these are classified as viruses. Indeed, more Browser Hijacker, Bacdau.vn included, is not considered a virus or ransomware. Viruses and ransomware will damage your PC in a direct way, Browser Hijacker is only after your attention and money.
Chances are that you were infected with Bacdau.vn way before you actually noticed it. They achieve that by hiding inside installers. Have no fear – we are here to help you with this issue. Below this piece of text you shall find a few paragraphs detailing the functions of Bacdau.vn. Read these parts thoroughly before proceeding with the guide at the bottom. A well informed man / woman has limitless potential. The same applies to this situation as well.
How is Bacdau.vn best described as? What should I know about it?
As it was mentioned before – Bacdau.vn is an instance of Browser Hijacker. Let us start by saying that it is completely useless for you. It gives you no real benefit. On first glance, some of them may have a semi-complete functionality – possibly one that they have advertised as a feature. Regardless, it is very easy to spot the offenders from afar. The programs in question generally appear half-finished and unpolished, mainly because the developers did not spend any real effort on the program’s front end. The back end is what really counts – the annoying ads. They are delivered differently, but generally boil down to 3 forms. You can read more about them below:
In-text ads have the most cunning nature. They take the shape of hyperlinks and hide inside the text of the web page. They are easy to spot, because – for the most part – they appear to be out of place. In some rare occasions, hovering your mouse over it can cause a window to appear.
Banners are the next offender and they are by no means small. They are usually large in size and occupy the edges of the web page – the top, bottom and sides. They aren’t as obstructive as the remaining two, but their sizes makes up for this fact.
Pop-ads are probably the most annoying form of ads you will ever face. They appear as massive, sizeable windows that show ads across the entire web page. Sometimes, they detach from your browser window and inhabit their own, separate window. Regardless of their appearance, their most prominent feature is their pop-up behavior – the ability to quickly and suddenly pop an ad in front of you.
How do I avoid it in the future?
A lot of unwelcome software ends up on your computer partly because of something you did or did not do. Here’s how to avoid unwanted Browser Hijacker and similar programs.
Carefully select what you download to your computer. Make sure you are of real need of the program you are planning to install. If you do not recognize the maker / publisher of the software, read about him carefully on his website (if available). If it sounds too shady, do not make unnecessary risks and just avoid the software altogether.
Read licensing agreements. It can seem very daunting to read these agreements, but to play it safe, don’t just scroll to the bottom and click the “I accept” button when installing freeware. Read the agreement carefully and try to spot any information-gathering phrases inside it. If that happens to be the case, again, avoid the software.
Beware of clickable advertisements. Just like the Browser Hijacker themselves, beware of flashy ads on websites you visit. Clicking them may lead you to a dark place where you may attract more Browser Hijacker.
