We are very thankful to you for visiting our page. However, your reason for choosing us as a source of information and help might be that you have had some problems with a certain piece of software, probably causing the incessant appearance of unwanted and quite disturbing pop-up ads. This program’s name is Tabcontent and it is a part of the Browser Hijacker family. However, does all that information ring any bells to you? We have assembled the following article with the simple purpose to help you solve your recent issues. Please, continue reading to find out more about the typical features of Tabcontent, as well as more about the potential unpleasant consequences related to it. Below is a guide that will walk you through the process of removing this program from your PC.

Tabcontent – a typical version of a Browser Hijacker

No description may fit this kind of software better than this one: the programs known as ad-producing ones are known by the common name Browser Hijacker. In fact, they have been created with the single purpose of displaying as big a number of ads as they can. From that description we can assume that Browser Hijacker works basically as a marketing tool and is specialized in promoting products and services.

Before we proceed with any further details about its nature, let’s mention a few distribution methods so that you can have a clearer idea of why Tabcontent functions in such a way.  Any innocent user might get infected with ad-generating programs via various means (from a torrent to a spam email). Despite that, the most effective way of spreading Browser Hijacker continues to be by mixing it with other software and offering the combo for free. This strategy appears to be pretty profitable, as many developers benefit from it in two ways – first by popularizing their own pieces of software; and second – by exploiting the pay per click scheme and earning huge profits from the generated ads. Now you are aware that many programmers might be willing to distribute Tabcontent along with their programs, because each displayed pop-up, banner, new browser tab or other type of an ad in fact increases the amount of their income.

Tabcontent “Virus” – malware or not exactly?

A lot of people around the web think of Tabocontent as a “virus” or malware. However the truth is different. The experts in the field of cyber security have never classified Tabcontent or any other Browser Hijacker-like product as a virus. A browser Hijacker doesn’t possess any of the characteristic features of the popular kinds of malware like: crashing systems, spying on users via their own webcams, destroying or encoding data (like Ransomware typically does) or exploiting any program or system weaknesses.

Nonetheless, some professionals may still identify Browser Hijacker-based programs as PUP’s or potentially unwanted programs.  While they do not represent really serious danger, some of them might still possess some rather questionable features. Let us start with an example – maybe you have noticed that the ads which have been irritating you normally promote only products that you have recently been searching for on the Internet. Tabcontent’s ability to guess your probable preferences by exploring your browsing habits could be rather shady. Another possibly bothering characteristic is that sometimes the number of the produced pop-ups could be so great that they may consume an incredible amount of system resources and make your PC not responsive.  Also, it is speculated whether some of those banners or pop-ups might actually redirect you to pretty suspicious websites, infested with viruses, some even as dangerous as the infamous ransomware.

How to handle Browser Hijackers?

First of all, it’s important for you to know that it is in fact easier to avoid such programs than to handle them after they have contaminated your machine. However, in case you are really irritated by those ads, you can use our removal guide below to set your PC free from those naughty companions. If you are just expanding your horizons by reading the article, you might be interested in some functioning prevention tips. Here is a list of some carefully chosen ones:

  1. Pay special attention to the installation process of any new program. Consider only the Custom feature of the given installer: a sensible and effective option for the completion of that process. Only this option will let you know whether there is any Browser Hijacker lurking in the given bundle and allow you to opt out of it. No more installing by Quick/ Typical/ Automatic or Default features.
  2. Think in a long-term perspective. Your cyber security is worth more than visiting any suspiciously looking but tempting website. Learn to avoid any possibly shady Internet addresses.
  3. Do your PC a favor and install a good-quality anti-virus program on it. Its long-term effects will repay every extra cent spent on purchasing it.
