Browser hijackers aren’t the most pleasant of programs to deal with and its latest representative called Fake Microsoft Warning Virus Scam is by far no exception. Once you’ve been infected by a browser hijacker, it’s very difficult to remain ignorant of that fact. Programs like these are actually very keen on making themselves noticed, so we’re guessing that you came to conclude that your PC had indeed been invaded when your Chrome, Firefox, Edge, Opera or other popular browser suddenly started behaving very oddly. We mean the change in its homepage, as well as the replacement of the old default search engine with a new one, which on top of all else also tends to initiate seemingly random and uncalled-for page redirects to various sponsored websites. In addition to the above, browser hijackers also tend to integrate ad-generating components within the users’ browsers, which results in a constant, never ending flow of popups, banners, box messages, in-text links and various other online ads. How do you make this advertising nightmare go away and how do you finally restore your previous browser settings? We will show you how to do that in our professional removal guide, which you can find below on this page. But do read through the following few paragraphs first, in order to gain a better perspective of Fake Microsoft Warning Virus Scam and what it’s up to.

Why browser hijackers behave the way that they do

The generation of the numerous ads may come across as random and many users find themselves wondering what their point is. Well, it’s really quiet simple. There are the products vendors and the service providers who would like to offer their products and services to the public, which is generally always done by means of online ads. hence, the more ads users are exposed to, the more likely they will be to purchase what those ads are promoting. You need to first find out about what you’re buying, if you’re going to buy, right? So, the same obvious principle applies here. One the other hand, we have the browser hijacker developers, who are just as invested in the ad generating process as the vendors. Why? Because they profit based on the number of times you or any other affected user clicks on the said ads. In fact, they earn revenue in accordance with remuneration systems like the Pay Per Click scheme, which foresees a small amount of money for each and every click.

However, this drive to gain as many clicks as possible leads to the developers often resorting to various techniques that don’t gain much approval among both regular users and cyber security experts. For one, in their pursuit of higher revenue, browser hijackers like Fake Microsoft Warning Virus Scam bombard you with ads, making it nearly impossible to dodge them, therefore, you inevitably end up clicking on this banner or that popup. Not to mention the deceitful tactics, where ‘Close’ and ‘X’ options don’t actually terminate and ad, but just redirect you to wherever that ad was set to send you. But there’s a more important and less obvious tactic that these programs use and it involves watching your online browsing patterns and taking them into account when generating their ads for each specific user separately. They can watch your latest search requests, or the pages that you spend the most time on. Even those you bookmark or favorite can tell the hijacker what it is you might be looking for in a product or a service.

Then, based on this data, the hijacker can start showing you ads that are relevant to your browsing habits and, therefore, to your interests. But aside from this being a blatant privacy violation, programs like Fake Microsoft Warning Virus Scam also have the capacity of exposing users to computer viruses and various harmful online threats. Unfortunately, though browser hijackers are not themselves malicious or in any way considered viruses, their many ads could risk getting your infected with something of the rank of a Trojan horse or ransomware, because hackers increasingly often rely on online ads to have their malware distributed to the end users. With this in mind, we strongly advise our readers to try and abstain from clicking on any online ads, no matter how trustworthy they may appear. It would be far easier and safer to simply remove the program generating the majority of them, so as to minimize the risk of a chance encounter with a real virus.
