If Informistio has integrated with Chrome, Firefox or another web browser of yours,  this article is just for you. You are most probably here because you are looking for a way to remove this strange software from your computer and get rid of all the intrusive ads, pop-up messages, and banners it keeps throwing at you whenever you try to surf the web, or because you have failed to uninstall the homepage or the search engine changes that this program has most likely imposed on your browser without your approval. If that is the case, here, we’ve created a removal guide to help you fix those things. You will find it at the bottom of this page, along with a professional removal tool that can help you remove Informistio without any trouble.

What you are dealing with is a program commonly known as a browser hijacker. A browser hijacker is not a virus or malware that can damage your computer but it is still software categorized as potentially unwanted. For the most part, this type of software is legal, but there are some actions that it performs that fall into a “grey-area” and may be considered quite unpleasant.

The Informistio Virus

Browser hijackers like the Informistio virus are known for their ability to track your web browsing activity and analyze it closely. The Informistio virus do that with the idea to produce more ads that would match your preferences.

Ideally, this will make you click on them more, which is important to the software developers of these apps as they get financially rewarded every time someone clicks on one of the many advertisements the browser hijacker generates. Of course, many people may be uncomfortable with the idea that someone is keeping tabs on their online behavior and may prefer to uninstall Informistio just because of that. Moreover, the questionable reputation of programs like Informistio and Captcha Source Center among users is also due to the fact that the developers may often sell the collected “traffic data” to third parties.

Another good reason to remove such software is the ability of the browser hijacker to initiate redirects to random web pages. For example, when you type the URL address of a particular website, the hijacker may first redirect you to a sponsored site of its own instead of directly land you on the page you desire. That may be a bit frustrating, but it also could hide security risks since you can never know whether the website you get redirected to is safe or if it has been compromised by a Trojan, a Ransomware, or by some other malware. Fake ads may also expose you to danger, therefore, clicking on anything that Informistio displays may not be a good idea. Moreover, malicious advertisements (malvertisements) can often blend with the regular advertisements on display and hackers can easily attach harmful payload to any of them. Sadly, it is difficult to distinguish the malicious ads from the regular ones and if you happen to click on one of the harmful ones by accident, you may easily download a virus, a real Trojan, or a stealthy Ransomware infection.
