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

Mybrowser-search is a browser hijacker application which promotes itself as a helpful addition to browsers such as Chrome, Firefox, and Internet Explorer. However, some users have called this application a “virus” and have reported some rather unwanted behavior related to its activities. Some customers have had their browser homepage and/or search engine replaced by some sponsored ones promoted by Mybrowser-search without their permission and have noticed some new toolbars and new tab changes, which they have not approved. Such behavior is typical for applications from the browser hijacker type and is not intended to cause harm to the users and to their computers. Most hijackers are usually programmed to make changes to the users’ browsers in order to advertise certain tools, search engines, homepage domains or other sponsored ads, pop-ups and commercials. More often than not, applications like Mybrowser-search are able to gain the users’ direct (or indirect) permission to redirect them to certain promotional websites in order to boost those sites’ traffic and visitor counts. Many people, however, see such applications as potentially unwanted and seek methods to remove their changes and have them uninstalled mainly due to their aggressive page-redirects and invasive browser changes.

How can Mybrowser-search invade your system?

The “infection” with a browser hijacker such as Mybrowser-search is definitely not as stealthy as the infection with a Ransomware or a Trojan virus. However, it may still happen in many ways and without you realizing it. When you visit different ad-supported websites, freeware or shareware platforms or torrent sites, you may accidentally download and install such software, believing that you are adding a helpful feature to your browser. Performing a careless installation of a free program bundle is yet another way to invite an ad-generating software into your system. Different spam mail attachments, free download links and ads, when opened/clicked upon, may also prompt you to download and install such tools. That’s why you should be mindful of the software sources you use and carefully perform installations through the Advanced/Custom/Manual options only.

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:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

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.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


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.

Possible negative effects of keeping Mybrowser-search on your system

In most of the cases, if you are not paying enough attention, an application like Mybrowser-search may invade your system without specifically notifying you about getting installed. However, once it gets into your browser, it doesn’t hide like a Ransomware or a Trojan horse virus and you can easily detect it as it places its browser changes and starts to flood your screen with ads and redirects. You may notice some new toolbars, desktop shortcuts or bookmarks, which you did not add previously. The default search engine may also get changed and you may be unable to access certain sites. Your hijacked browser may get slow and respond sluggishly. One of the most annoying things, however, is that every time you try to enter a specific web address, it may automatically get you redirected to some other sponsored pages, which may be completely unfamiliar to you and which you likely don’t want to visit. The objective behind this behavior is simple – to ensure that the browser hijacker can earn pay-per-click revenue by exposing you to specific promotional ads, pay-per-click links and websites and also by monitoring your online activities in order to later spam you with targeted commercials. This behavior is typical for most online advertising tools but if you don’t want to keep such software on your PC, you can remove it by following the instructions in the guide above and thus have all of the hijacker components completely uninstalled.
