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

There are many programs which are capable of imposing certain modifications (such as homepage or search engine replacements or new toolbars installation) to your default browser and use it to display hundreds of nagging ads and pop-ups. These programs are usually classified as browser hijackers and one of them is Mystart Search Virus. If this application has recently caused your Chrome, Firefox or Explorer to become unresponsive to your searches and to redirect you to various sites full of nagging ads, pop-ups and banners, on this page, we are going to show you how to effectively remove it. Some people have recently asked us if Mystart Search Virus is some kind of a virus and can it be dangerous for their computers. Fortunately, this is not the case and even if this program may cause some irritation, it definitely cannot be as malicious as a Ransomware, a Trojan horse or some other virus-like infection. In the next lines, we will explain you what exactly can a browser hijacker do and what are the potential issues you may face if you don’t uninstall it from your system. You can also read about how to effectively prevent such software from invading your browser in the future, so stay with us until the end as there is a lot to learn.

What is a browser hijacker?

It is not a secret that the web space is the perfect place to advertise. With more and more businesses, switching from traditional to digital marketing, they desperately try to promote their products and services as much as possible, and one of the most commonly used and aggressive tools for that in that is the browser hijacker. Mystart Search Virus is a typical representative, which is developed and programmed to serve the advertising needs of the online industry by hijacking the users’ browsers and making them display certain promotional sites, ads, and offers. Its hijacking activity may also be related to some sudden page redirects, installation of some new toolbars, search engines or homepages. The reason for this invasion in your normal browsing settings is usually the strive of the hijacker owners to drag traffic and clicks to the sponsored web pages and ads and earn from Pay-Per-Click campaigns.  This way, they can gain some revenues to support their businesses. However, the advertising materials that the users frequently get exposed to, may be quite aggressive, difficult to close or remove, and may cause some serious browsing-related disturbance and irritation.

What are the usual browser hijacker sources?

Driven by the desire for more profits, the developers of browser hijackers often distribute them along with some other attractive and mostly free software, by placing them inside the installer. This way, if the users download and install the free software installer through the Standard/Automatic option, they will automatically install the bundled browser hijacker as well.  Such packages (aka bundles) can mostly be found in open source platforms, direct free download links, online installation managers, spam messages, torrents, emails with attachments, etc. In order to prevent the installation of the potentially unwanted programs they may contain, we strongly advise our users to always read the EULA and use only the Custom/Advanced installation option when they have to run the installers.

Mystart Search Virus is not a virus, but this is what it could do:

As we already said above, neither Mystart Search Virus nor any other program from the browser hijacker family can be seen as a serious threat to your computer. Basically, this type of software does not contain malicious scripts, unlike the Ransomware, the Trojans, and the other nasty viruses. That’s why the security experts don’t see a real reason for the users to get panicked if a program of this type takes over their browser. In most of the cases, the browser hijacker can easily be uninstalled from the system without any harmful or destructive consequences and in the removal guide below you will find the exact instructions for that.

While operating, however, a piece like Mystart Search Virus may cause some irritation of the following type:

  • Your homepage or search engine may be replaced by some strange unfamiliar ones.
  • Practically any browser, Chrome, Firefox, IE, Edge or some other, can become unresponsive to your searches, and get busy in displaying hundreds of unwanted advertisements.
  • The browser overall performance may get slow. It may take it ages to load the pages you want and you may suddenly get redirected to some other sponsored sites.
  • Some traffic data about your recent online activity may be collected and transmitted to the developers or third parties for the purposes of marketing.
  • In some rare cases, the hijacker may indirectly expose you to a harmful ad, a misleading link or compromised web page if a hacker secretly loads some malicious payload inside the ads that get displayed. This may lead to the infection with some nasty virus or some other computer threat.
