This page aims to help you remove Utilitool. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.


Utilitool is a potentially unwanted browser extension developed to display ads during web browsing sessions. To perform this task, Utilitool will typically install ad-generating components in the default browser and replace the search engine or the homepage with ones that constantly generate ads.


The Utilitool Virus will interfere with your browser searches.

The first encounter with a browser hijacker can be stressful if you don’t know exactly what’s happening. The unauthorized homepage and search engine changes that take place in the main web browser may panic a lot of web users and even make them believe that they have somehow been infected with a virus. However, these changes, as well as all the automatic redirects to different commercial-filled sites, are not symptoms of a malware infection but typical signs of the presence of a browser hijacker on your computer.

That’s why, if you have recently detected Utilitool on your machine, you don’t need to get stressed about it – this is not a Trojan, a Ransomware, or another type of harmful software. What you are dealing with is a browser hijacker created to fill your screen with sponsored ads, banners, and pop-ups during your web browsing sessions. In the next few paragraphs, we will tell you everything you need to know about it and will help you remove it from your Chrome, Firefox, Edge, or Safari browser quickly and easily.

Utilitool on Chrome

Technically, a browser hijacker such as Utilitool is software created for online advertising purposes. Therefore, it is not expected from such software to harm your computer the way that a real virus or malware from the ranks of Ransomware and Trojans could.

Yet, browser hijackers like Utilitool are often seen as potentially unwanted programs. They won’t damage your computer if you don’t uninstall them but they may cause some irritating issues, which could give you a good reason to remove them without at the first opportunity you get. For instance, Utilitool and other apps like it can hijack the main web browser and impose some potentially unwanted changes on it. As we mentioned above, these apps can replace the homepage URL with another one, install a new search engine, install new toolbars, set some redirect buttons, and, in general, hijack the browser in order to carry out their advertising activities. Besides, such programs can expose web users to online ads of all shapes and sizes including pop-ups, banners, box messages, redirect links, etc, some of which may not be safe.

Dealing with all those changes on a regular basis can not only be very frustrating but could also land you on random web locations that might have been compromised and may contain malware. Besides, when bombarded with hundreds of ads during every browsing session, you can easily end up running into some fake online ad or one that hackers have tampered with. Ads like these may often carry viruses like Ransomware, Spyware, and Trojans, and, sadly, it takes just one click to get infected.

Fortunately, now that you have been informed about the risks, you have the chance to remove Utilitool right away and avoid possible interaction with misleading content. What is more, once you uninstall the browser hijacker, you can easily restore browser settings you prefer and regain full control of the hijacked browser.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.

To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.
