This page aims to help you remove W3sercher.biz Virus. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.
If your web browser is constantly being redirected to W3sercher.biz, or advertisements are popping up while you browse the Internet, then your computer may be infected with browser hijacker.
W3sercher.biz Virus is a special type of program that aims to alter the main configurations of the default browser (be it Chrome, Firefox, Explorer or another one) and to use it as a tool for aggressive online advertising. When it is installed, W3sercher.biz typically may change the home page and the search engine and to install some additional components that initiate automatic page-redirect to specific sites. The program may also display ads, pop-ups, banners, and different promotions during the regular web browsing and redirect the users to third-party sites with a questionable reputation. Due to these activities, W3sercher.biz falls under the category of Browser Hijackers and is considered as a potentially unwanted program. If you have this program on your system and you struggle to effectively uninstall it or you don’t know how to remove its changes, our “How to remove” team has prepared a detailed removal guide on that. The good news is you don’t need to be an expert to follow the instructions because W3sercher.biz is not some harmful virus, a Ransomware, a Trojan or another nasty threat that require professional assistance. Yet, for faster and effective uninstallation, you may like to use the suggested W3sercher.biz Virus removal tool. Before you scroll down, however, let us tell you a few more words about the specifics of the Browser Hijackers in general and the potential negative effects of keeping them on your computer.
The W3sercher Virus
A Browser Hijacker is a piece of software which can commonly be mistaken for malware. In fact, many web users, who have never encountered a page-redirecting and ad-generating program of this kind, can get quite intimidated when they notice how the hijacker alters their computer’s browser settings and redirects them to websites they did not intend to visit. That’s why it is not surprising that in many forums different web users may refer to programs like W3sercher.biz as a virus and may desperately seek help to remove them. In reality, however, the Browser Hijackers are not malicious programs and have nothing in common with real threats such as Trojans, Spyware or Ransomware. They are just tools of the online advertising industry which use a rather aggressive approach to promote certain products, services, and web pages.
Many Browser Hijackers come in the form of add-ons, also known as browser extensions, navigational aids, or toolbars. Often these elements can improve the experience on a website by providing interactive content, relevant promotions, and helpful redirects. However, some hijacker add-ons may cause the computer to stop responding or display unwanted content, such as pop-up ads, banners, and click-prompts that lead to unfamiliar web locations. In those cases, they are considered as potentially unwanted and the users are advised to uninstall them as soon as possible as this is the best way to save themselves from the aggressive ads disturbance and potential redirects to shady websites. Fortunately, you can easily recognize if your browser has been hijacked – there will most probably be some unapproved homepage changes and when you try to open a new tab, you will be automatically redirected to some sponsored site. The fastest way to get rid of the unwanted software is to use a professional removal tool, such as the one below, or to follow certain manual removal steps.
|Danger Level||Medium (nowhere near threats like Ransomware, but still a security risk)|
|Symptoms||Changes in the browser’s homepage, new search engine, new toolbars and automatic page-redirects.|
|Distribution Method||Spam messages, software bundles, free automatic installers, torrents, ads, shareware.|
