Gum.criteo.com is a web browser component that is known to cause a lot of browsing irritation. However, the good news is that Gum.criteo.com is not a dangerous computer virus or a malware such as a Trojan Horse or a ransomware and can be removed without any significant negative consequences from your Chrome, Firefox, Edge or any other web browser.
That being said, it’s always a good idea to be careful with browser hijacker programs like Lookaside.fbsbx.com, Main Captcha Top and uninstall Gum.criteo.com before it takes over your default web browser completely because if you let it do so, the program may expose you to dangerous web locations where the chance of meeting Trojans, ransomware and other computer viruses is very real.
From the moment it starts to operate on your computer, Gum.criteo.com typically installs a new search engine into your browser and changes the default homepage address with some sponsored website that spams you with hundreds of pop-ups, banner messages, and click-bait ads the moment you land on it. The role of these changes, which typically aren’t user-approved, is to activate an intrusive page-redirecting and ad-generating activity from Gum.criteo.com on the screen of the main web browser that is aimed at promoting different websites, and their related products, services, and software.
While most browser hijackers are not viruses, they are typically tough to uninstall. And this is what confuses web users a lot.
The Gum.criteo.com Malware
Unlike a regular web browser extension, an app like the Gum.criteo.com malware may not have an uninstall menu from where it can be easily removed. And this makes the successful deletion of all the hijacker-related components a challenging task, especially for unprepared web users.
Since you are on this page, however, we will help you cope with Gum.criteo.com by giving you our removal guide, which includes all of the details you would require to remove the irritating program successfully. The guide provides a series of manual instructions that should be completed in several steps.
However, if you believe your degree of technological expertise would not be enough for you to complete the guide carefully without deleting something else, you still have an option to use professional removal software like the tool that we have introduced in the guide. It will save you time and nerves and will eliminate the unwanted software within seconds.
The importance of keeping your PC hijacker free.
The ads irritation, the frequent page-redirects and the unauthorized modifications in the browser’s search engine, homepage and toolbars is typically enough for most users to decide to remove the browser hijacker app without regrets. However, there are a few more good reasons why apps like Gum.criteo.com should generally not be kept on the computer.
The major one of them is linked to the aggressive web promotional activities, which are often not regulated or poorly regulated. A hijacker like Gum.criteo.com may display a number of on-screen banners, pop-ups, redirect messages, click prompts and similar advertising materials that may be dangerous for the end user or may be virus-infected. And if you click on a web link or an add that turns out to be misleading, or you interact with the content of a sketchy website that the hijacker has redirected you to, you may land your computer with a terrifying malware, like a Trojan Horse virus or a file-encrypting ransomware infection. So, compared to that risk, it is much easier to get rid of the hijacker itself and prevent a possible encounter with sketchy web materials.
