Remove Background_Vault Virus

In the paragraphs you are going to read we are talking about a program from the infamous family of the browser hijackers. It is called Background_Vault Virus. Among its at times irritating features could be the broadcast of different ads like banners, boxes or pop-ups; the display of often unfamiliar search engines and homepages; and the potential redirecting to somewhere on the web. When it comes to this software group, we can also point out that all the programs that belong there may only affect one part of your system – all the browser apps you have installed, from Chrome to Explorer, Opera and Firefox. Simply continue reading if you are interested in all the details about this specific hijacker and/or the whole software family in general.

The usual features of browser hijackers generally and Background_Vault Virus specifically

What we can say for sure about this sort of software is that the programs belonging to it are adept at advertising various things via producing online ads; and causing your browsers to behave differently from the way they normally do. All hijackers have been created with this particular purpose – to show advertisements to the users and in this way encourage them to buy/order the promoted products or services. To be precise, there is nothing surprising, shady or illegal about this way of behaving. It’s just the mutual efforts of producers and programmers to achieve the best possible way of promoting whatever they offer. The benefits from this kind of advertising are for both of the involved parties – the ones offering something, and the ones ensuring the success of the ad campaigns.

Why could Background_Vault Virus sometimes be falsely regarded as a malware version?

In general, there is actually nothing malicious about Background_Vault Virus in particular, or its sibling programs. Despite that, a lot of users worldwide could still mistake it for a virus. This could occur because of its quite shady reputation: the generation of pop-ups could really irritate or confuse some users, and they may report this problem as rather disturbing. That’s the reason why hijackers are often seen as potentially unwanted. Honestly – there isn’t any relation between any hijacker and any form of malware (Ransomware, Trojans). In fact, these software types have so many differences that we can’t relate them in any way. While Ransomware and Trojan horse viruses could damage everything inside your system – programs and data; Background_Vault Virus, for instance, cannot access anything different from your browser apps and their history records.

Getting infected with a hijacker – possible way of happening

When we talk about the potential distribution methods of ad-broadcasting programs, they might be various in number and in nature. From spam and shareware to program bundles, Background_Vault Virus may be lurking everywhere. The most popular source, though, appears to be any software bundle. These free software sets (which may contain new apps and recently developed games) could seem to be very interesting to you; and you may want to download or try some immediately. The potential issue with them is that they may involve ad-spreading programs (such as browser hijackers and Adware), and perhaps you will NOT be informed about that.

However, you may be more than willing to install the entire bundle you’ve downloaded. Really, that’s how the ad-production mess will typically start. For the purpose of avoiding such kinds of irritation, you have to install any bundle (or any program, game or app from it) in a clever way. By the proper way we want to say – the installation method,  which gives you the opportunity to perform everything about the installation manually. The only wizard features, which may ensure this kind of an installation process are: the Custom (often could be seen as Customized); and the Advanced one. Select one of them, and you will get to choose what to incorporate into your system and what not to.

The way to avoid any hijacker

The process of prevention, in the case of avoiding Adware and hijackers, starts with the aforementioned way of installing any bundle or software on your PC. Moreover, you have to learn to avoid the places where such Internet annoyances might be lurking like torrents, video-streaming web pages or fake online advertisements. The removal of such programs is possible, you just have to turn to the instructions in the Removal Guide down here.
