How irritating is this virus?

This page aims to help you remove  the Critical Chrome Update Scam “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Browser hijackers are certainly a nuisance and are considered to be among the most annoying and useless programs (from the regular user’s perspective) that you may ever come across online. But is there more to them than just what we see on the surface? Today we will be looking at a specific representative of this software category better known as Critical Chrome Update Scam “Virus” and if you are familiar with it – stick around it. We will tell you what lies beneath all the strange changes that it has most likely enforced on your Chrome, Firefox, Edge or other browser, such as the new homepage and/or new default search engine that keeps redirecting you to different unfamiliar webpages. What’s more, though, we will also show you the most effective method of dealing with Critical Chrome Update Scam “Virus” and all its annoying changes and that is removing it from your system. For that purpose we have prepared a detailed removal guide just below this article, but we do insist that you finish reading the article first, as it contains important information regarding Critical Chrome Update Scam “Virus” and other pieces of software like it.

What hides behind all the strange browser changes and what does this hijacker really want?

The purpose of the numerous ads that Critical Chrome Update Scam “Virus” tends to flood your browser with, including the many popups, popunders, banners, box messages, etc. is simple and boils down to making a profit. On the one hand, the vendors of all the endless products and services that get advertised, who make a profit by gaining more exposure for the things they’re selling, and therefore more customers. But on the other hand, the browser hijacker developers are often equally invested in the whole advertising process, because they, too, benefit from it. Thanks to remuneration schemes such as the infamous Pay Per Click system or PPC for short, the developers can profit from the clicks made by users on the said online ads. It’s important to be aware of this fact, because it is what dictates the hidden behavior of programs like Critical Chrome Update Scam “Virus”. Let us explain.

In order to maximize their profit and increase the effectiveness of their advertising campaigns, developers often program hijackers and other similar software to access the browsing history of the affected users. They do this in order to extract information related to their latest searches, the type of content they like and share on social media, as well as the websites they tend to hang around most on. This allows the browser hijacker, be it Critical Chrome Update Scam “Virus” or another one, to determine the type of products and services it has in its arsenal that will have a higher chance of attracting each specific user’s attention. Then, taking this into consideration, the browser hijacker typically alters the generic or random ad distribution and coordinates it with the user’s estimated preferences. That way, it can increase the chance that its ads will get clicked, as you will be more inclined to interact with a certain ad if it has something to do with your hobbies or current interests, than if it were just some random one.

However, the problem with this practice is that it is undoubtedly a privacy violation and is most often frowned upon in the online community. In fact, this is partially why many security experts tend to categorize browser hijackers and other ad-distributing programs of the sort as potentially unwanted programs or PUPs. But if that isn’t enough for you, there’s another factor worthy of your consideration that further contributes to this categorization.

We’re talking about the possibility of programs like Critical Chrome Update Scam “Virus” exposing you to different online viruses, such as ransomware, spyware and Trojans. This is not to say that Critical Chrome Update Scam “Virus” is a virus itself – that’s far from the truth. As a matter of fact, we would like to underline the opposite and emphasize that browser hijackers are not thought of as malicious, as they do not possess any virus characteristics. Nevertheless, they can put you and your system at risk of contracting a real virus, even if it’s unintentionally. The numerous ads can make it easier for you to bump into the so-called malvertisements, for example, which are ads that have been injected with malware. Therefore, we highly recommend abstaining from interacting with online ads of any type.
