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.
