SearchConverterHD is a browser hijacking application that frequently annoys web users with unwelcome pop-up advertisements in their browser. To operate, SearchConverterHD needs to connect itself to the main web browser in the system and to modify its homepage and/or search engine settings so that more advertisements can be displayed on the screen.


The SearchConverterHD will redirect your browser when you try to use it.

It doesn’t matter whether you use a popular web browser like Chrome, Firefox, Edge or any other browsing application, because almost every browser can be hijacked and have its settings changed by SearchConverterHD. Users usually detect the browser hijacker right away, as their regular web browsing activity starts to be disturbed by hundreds of sponsored advertisements, pop-up messages, banner ads and on-screen alerts that are difficult to remove and cover the content of the visited pages.

The replacements in the browser’s homepage URL and the change of the default search engine are two more symptom of the intrusive software that cannot be overlooked. They may be completely removed and replaced with some new ones that are totally unfamiliar to you. The role of the new homepage and the freshly installed search engine is to ensure that users are constantly being redirected to partnering websites and their screen is filled with sponsored search results.

Thankfully, SearchConverterHD is neither a virus that is meant to damage your computer nor malware (such as Ransomware, a Trojan, Spyware, etc.) that seeks to blackmail you or steal your data. This program actually claims that when you integrate it with your browser it will enhance your web browsing experience. Most of the time, however, SearchConverterHD simply tries to promote specific products, services, software and their related websites, so that its developers can generate pay-per-click and pay-per-view revenue from the visits and user clicks on the displayed advertisements.

However, many people see this browser hijacker as an annoying and unwanted piece of software and prefer to uninstall it from their browser. Additional irritation is caused by the fact that SearchConverterHD normally does not allow users to reset, undo or uninstall the unauthorized browser changes. It basically imposes the new settings and pressures the end user to deal with the newly installed search engine, homepage and new tab configurations. This is why people who don’t want to adapt to the hijacker’s “improvements” have no other option but to completely uninstall it and permanently remove its components from their browser.

Of course, for some people, it may not be that irritating to see ads during their web browsing sessions. Still, we feel obliged to warn you about the potential risks of keeping such software in your system. The main one is that if you are careless about the random pop-up messages, banner ads, redirect links and colorful notifications that a program such as SearchConverterHD can flash on your screen, you may easily become a victim of malicious advertising. Misleading web links, fake pop-ups, and too-good-to-be-true web offers may easily appear on your screen thanks to a browser hijacker and you may get tricked into clicking on them, downloading unwanted software, wasting your money by purchasing some unnecessary or low-quality products or services and even participating in web scams. Viruses and other security threats, especially Trojans, Spyware and Ransomware are well known to use malvertising as a method for their online distribution. With all this in mind, the best piece of advice we can give you is to stay away from everything that SearchConverterHD displays and regain control of your web browser with the help of the instructions in the removal guide below.
