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

Applications like Onesignal.com may cause some real web disturbances when it comes to surfing the Internet. These pieces of software are commonly classified as Browser hijackers. They often have the ability to change the settings of your Chrome, Firefox or Explorer browsers and to add some new homepages, search engines, toolbars and automatic page-redirect services. It is typical for the hijackers to display hundreds of unstoppable ads, pop-ups, banners and blinking boxes, which can be very hard to remove. The good news, however, is that on this page, you will find a step-by-step Removal Guide with instructions on how to safely uninstall such hijackers from your system and how to get rid of all of their changes.

Generally, the Browser hijackers are not really all that harmful. They are developed to generate promotional content of various kinds (links, ads, sponsored web pages, pop-ups, toolbars, etc.) on the users’ screens every time they open up their browser. This is not an illegal activity and has nothing to do with computer viruses or malware programs such as Trojans, Ransomware or Spyware. However, the way such applications operate may cause some significant disturbances, undesired page-redirects, and exposure to irrelevant or questionable content. Onesignal.com, for instance, is highly likely to conduct the activities described above because the moment it gets in your system, it will most probably alter the settings of your default browser and will start to flood your screen with ads, new tabs, and pop-ups that wouldn’t go away if the hijacker remains operation on the computer. You may also notice that your search queries may start to get frequently redirected to some promotional sites or pages that have nothing to do with the content that you’ve been actually looking for.

These redirects, ads, and links are usually sponsored and they aggressively try to offer you different products and services with the idea of making you click on them and potentially buy something. That’s why they appear all over your screen and oftentimes when you try to close them they actually redirect you to their sponsored pages. Basically, every click that the intrusive commercials get converts into income for the creators of the Browser hijacker thanks to advertising methods such as Pay-Per-Click or Pay-Per-View. The generated revenue usually helps the developers to support their business or to distribute different software for free while earning money from their ads.

Are Browser hijackers dangerous?

Many web users think of the annoying browser hijackers and their activities as some sort of computer threats or viruses. This is quite common because the rather aggressive way these apps operate may indeed be very irritating and may disturb the normal web browsing. However, the page redirects, the hijackers are actually not typically capable of causing some actual harm to the system (at least not on their own). Their role is to simply advertise. That’s why, most security experts do not consider softawre like Onesignal.com as a security threat. However, even though the hijackers do not contain the malicious code found in insidious viruses like Ransomware or Trojan Horses, they may still be quite annoying which is why it is usually recommended to have them uninstalled.

For instance, such programs may alter the settings of your browser by installing some new homepage, a search engine or an automatic page-redirect service, which may mess with your search results and display some sponsored content instead of the actual content that you’ve been searching for. In some cases, it is not excluded that you may come across misleading or inappropriate content or even some questionable pages and sites. For this reason, we would generally recommend that our readers do not to click on the content that the hijacker generates.

Those who want to stay on the safer side are advised to fully uninstall the ad-generating software in order to eliminate the possibility for running into any potential security hazards. This can easily be done with the help of a professional removal tool, such as the Onesignal.com removal tool on this page, or by following the steps in the manual removal guide from this page. And if you don’t want to have your browser hijacked again and again, it is also a good idea to avoid its most common sources. These usually are different software bundles and free application installers. However, browser hijackers and similar ad-generating programs may also be found in free download links, ads, spam emails, torrents, freeware platforms or shareware sites. That’s why, our advice is to keep away from them and also to always install new software on your PC through the Advanced/Custom installation options instead of the Quick/Default ones.
