Open4u Virus


Open4u

Open4u is a browser hijacking app, created to display sponsored advertisements and redirect prompts on every web page the users visit through their browser. Open4u can also promote different search engines, homepages, toolbars, and other browser components by replacing the existing ones with them.

The Open4u Virus will redirect your browser searches.

Open4u is a new representative of the browser hijacker category that usually displays multiple advertisements (such as pop-up messages, banners, text links, new tabs, box notifications, etc.) directly on the web browser’s screen during the browsing sessions. To ensure better control over the content that gets shown on the screen, the hijacker can typically install a search engine of its own and replace the homepage with one that automatically redirects to specific sponsored pages. No web browser is immune against being hijacked by an application like Open4u, therefore even web users who use well-known and safe browsers such as Chrome, Firefox, Edge, and Safari can experience the annoyance of the numerous advertisements on their screen and the imposed browser modifications.
This article, however, has been created in response to the growing number of web users who have been asking us how to deal with the different advertisements and the potentially unwanted browser changes that have been disturbing their web browsing activity. That’s why below we have published a removal guide with instructions that explain exactly how to remove Open4u and uninstall its changes.

A browser hijacker such as Open4u can become part of your system in many different ways. Sometimes, you may let it get installed when you visit a web page that prompts you to download some free applications. In other cases, you may get it installed when you download torrents from free file-sharing sites, or when you click on some spam message in your inbox and download its free attachment.

Among the diverse ways of browser hijacker distribution, however, the most commonly employed one is to bundle it into the software package of another free and attractive program, game, software optimizer, free audio or video player, etc.  Therefore, you should always read the EULA and check thoroughly the installers of any new programs in your system and especially the Advanced/Custom settings where programs like Open4u can often be found.

Can Open4u put your system in danger?

Browser Hijackers are generally harmless programs used for aggressive online advertising. Yet, the ads, banners, pop-ups and redirect links they display typically manage to irritate the end-users to such an extent that they consider such programs for some sort of redirect viruses and even put their name next to malware such as Ransomware and Trojans. However, in reality, programs like Open4u are not able to carry out the deceptive activities that a real Ransomware or a Trojan horse can perform.

Still, even though it is far from a virus, you might prefer to uninstall the browser hijacker and remove its ads due to a number of other reasons. For instance, such software can often interrupt your browsing sessions with irrelevant and annoying offers, promotions, coupons, notifications for different deals and similar commercial messages. And even if you try to put that disturbance aside, it will be hard to ignore the browser’s unresponsiveness and the sudden crashes that may take place every now and then due to system overloading with continuous page-redirecting and ad-generating processes.
