Browser hijackers certainly aren’t among the most desirable software types out there. Anyone who has ever had anything to do with these programs will surely agree with this statement. We’ve dedicated this article to breaking down all there is to know about browser hijackers in general, but also about a specific representative of this software category – “Your computer is infected. You have to check it with antivirus.”. “Your computer is infected. You have to check it with antivirus.” is one of the latest browser hijackers to be released and we’ve been asked by numerous of our readers to provide a removal guide for this program. They have all described the typical hijacker symptoms that are all the same for any popular browser, be it Chrome, Firefox, Edge or another. A changed homepage and a newly set default search engine will be the first indication of “Your computer is infected. You have to check it with antivirus.”’s presence in your system, in addition to the frequent page redirects that tend to follow. Read on to get a better understanding of what this hijacker is doing on your PC and at the end we will show you how to quickly and easily remove it, together with all the obnoxious changes that it has imposed on your browser.

What browser hijackers do and why

Programs like “Your computer is infected. You have to check it with antivirus.” are primarily focused on providing exposure for various products, services and websites by means of online advertising in the form of banners, box messages, popups, in-text links and similar materials. Obviously, the vendors and distributors of these services and goods benefit from this, because they will potentially gain more customers. On the other hand, however, there are the browser hijacker developers, who also benefit from this whole process. Thanks to the Pay Per Click scheme, which is a popular remuneration and system and online business model, they can profit from the paid clicks on all the different box messages, banners and popups that keep on seeping onto your screen. However, there are a few points that need to be made in regards to this system, because it’s not as crystal clear as you might think.

The main issue that both security experts and regular users tend to have with it is the fact that programs like “Your computer is infected. You have to check it with antivirus.” often have access to your browser’s history, meaning they can view all sorts of browsing-related info. They would mainly be after things like your latest online search queries, as these would give them better perspective on the type of content you’re currently interested in. They can then alter their ads flow to match your preferences, or in other words, the hijacker will then begin to display ads that match your estimated preferences. The problem here is that this is quite obviously a privacy violation. And while these programs cannot gain access to sensitive or personal information, the browsing data that they can obtain can later be sold to various other marketers and third parties – hardly a desirable outcome.

And if that’s not enough for you to want to get rid of this program – there’s more. For one, the presence of a hijacker like “Your computer is infected. You have to check it with antivirus.” can easily impact your PC’s productivity and even directly affect its speed. Due to the sometimes overly intense ad generating that goes on indefinitely in the background, “Your computer is infected. You have to check it with antivirus.” can put a strain on your PC’s resources and therefore start causing annoying issues, such as slowdowns, crashes, lags, etc. On rare occasions, things might even get as bad as leading to system crashes and BSOD. But there’s even more serious potential consequences to be considered, such as the risk of being exposed to actual viruses and threats of the ranks of ransomware, Trojans, spyware and others. These are by no means to be taken lightly and an infection could occur, for example, by bumping into the wrong online ad. Cyber criminals often use online ads, which they convert to malvertsiements (malicious advertisements) by injecting them with the malicious scripts of different viruses. As a result, these compromised ads become contagious transmitters of the malware in question and one click on them is often all it takes to get infected. With that in mind we would strongly recommend avoiding contact with any online ads that you may see, as visually it’s impossible to distinguish the legitimate ones from those that could potentially harm you. With all this in mind, you’re probably eager to finally get down to the removal process, for which you may use the below guide.
