Browser hijackers are not among the most harmful pieces of software that you can encounter, but still, they aren’t among the nicest either, because they often may cause you a lot of browsing-related disturbance. One of their latest representatives is Google Security Warning Popup Virus – a program, which once it invades you, is almost impossible not to be noticed because it usually incorporates with your default browser (be it Chrome, Firefox, Explorer, Opera, etc.) and imposes certain changes to its settings. These changes are usually related to the replacement of the current homepage or search engine with some other, unfamiliar one, the initiation of some sudden page redirects and the generation of different ads, pop-ups, banners and intrusive sponsored messages on your screen. Programs like Google Security Warning Popup Virus are actually specialized in the aggressive generation of advertisements and all of the modifications they initiate are all related to that ability of theirs. But how can one make the intrusive ads disappear and bring back its own browser settings? We have dedicated this whole article on that, and in the next paragraphs, you are going to find all the needed information to effectively remove and uninstall the hijacker along with all of its nagging pop-ups.

How the browser hijackers behave and why do they flood you with nagging ads?

Different nagging ads and pop-ups may appear on your screen when you are browsing the web and that is perfectly normal. Most of these ads are usually generated by the web pages that you visit and the moment you close them, they also disappear. When you have a piece of software like Google Security Warning Popup Virus installed on your computer, however, your entire browser may get affected and closing a certain page tab won’t make any of the popping messages disappear. What is more, instead of browsing the web in peace, you may find yourself frequently redirected to some unfamiliar sites, promotional pages, sponsored advertisements, ads, banners, links and all sorts of blinking boxes that aggressively prompt you to click on them. But why would this software behave like that? The reason is very simple – profits and advertising. The idea behind programs like Google Security Warning Popup Virus is to expose the users to as many ads as possible and bring profits for the people, who stand behind the browser hijacker. These people are usually the vendors and the service providers, whose offers have been displayed, and who will be more than happy if you click on their ads and buy something. Apart from them, the browser hijacker developers also benefit from the ad generating process thanks to methods like Pay-Per-Click, which bring them profits based on the number of clicks that the users give on the displayed ads. The strive of these two interested parties to make money leads to the implementation of some quite aggressive advertising practices like hijacking the users’ browser, redirecting their searches and streaming unstoppable flows of advertisements on their screen. These practices, commonly employed in browser hijackers like Google Security Warning Popup Virus, are not illegal according to the law, but they don’t gain much approval among the affected users as well as from most security experts.

Issues that browser hijackers may cause:

The intrusive advertising techniques that programs like Google Security Warning Popup Virus may employ have the potential to create incredible browsing disturbance and prevent the users from accessing the web normally. The aggressive ads generation, redirections, and browser modifications are usually unapproved by the users and they end up struggling with their consequences without having the option to stop, remove or uninstall them easily. What is more, in their attempts to gain more clicks and profits, the people, behind the hijacker, use some deceitful tactics. For instance, they tend to anyways redirect the users to the set sites or promotional content despite their attempts to close the displayed ads through the “x” button, or they often extract “traffic data” from the affected browser to gain more information about the users’ browsing habits, their latest web searches, bookmarks, and interests. These invasive practices help them position their advertisements accordingly and target their customers more precisely. However, this comes at the cost of the immense users’ disturbance and irritation.

Aside from being irritating, the browser hijackers may indirectly expose users to some online hazards like computer viruses, or malware like Trojans, Ransomware, Spyware and various other online threats. This may potentially happen if they interact with some fake, misleading or infected ad, or get redirected to illegal pages, which have already been contaminated. A lot of hackers and criminals tend to mask their viruses as ads and pop-ups, and it is not excluded that you may come across them in the stream of advertisements that constantly gets displayed on your screen. That’s why it is not a good idea to keep the browser hijacker on your system and risk being infected with some sort of a nasty Trojan or Ransomware virus. And even despite that, any security expert, whom you would ask, would tell you that browser hijackers don’t contain harmful scripts, nor can they cause you serious system harm, some sort of malfunction or corruption to you data and your software, uninstalling them from your system could save you from a whole lot of disturbance and unpredictable infections.
