Promodayz is a piece of software that enables auto-redirects of user searches to different sponsored websites that are loaded with pop-up advertisements. Users that have Promodayz on their device complain that their browser configurations have be modified by this software without their approval.


The Promodayz Virus will redirect your browser searches.

Typically, the majority of people who face a browser hijacker for the first time mistake it for a virus or malware (similar to Ransomware, Trojans, etc.) and cannot figure out how to remove it and why it is making changes to their browser without being authorized to do so. Promodayz, for instance, causes confusion and disturbance because it normally activates a new search engine and changes the homepage address to a different one that loads a particular website. The program may also add some components such as toolbars, page-redirect buttons and quick access menus to the browser that only clutter the appearance and generate various sponsored pop-up ads, banners and links when clicked on. These homepage, search engine and toolbar changes are only made with the idea to facilitate the ad-generating and page-redirecting activities of the browser hijacker and to ensure that every time the user opens their web browser, they get encouraged to click on some sponsored links and web offers.

Promodayz on Chrome

In case that you are getting redirected to sites you do not want to visit and your browser’s screen (be it Chrome, Firefox, Edge, etc.) is constantly bombarded with hundreds of pop-up advertisements, banners, colorful boxes and other aggressive commercials, it’s quite likely that you have Promodayz in your system. Promodayz is a browser hijacker that is usually used for marketing purposes and is not malicious. Yet, many users fail to understand exactly what this program is doing on their computer and seek to uninstall it as soon as possible.  

The Promodayz Virus

The main challenge that users face when dealing with the Promodayz Virus is in regards to removing these changes and uninstalling the hijacker that imposes them because, in most cases, their attempts to get rid of the intrusive software fail. This is because browser hijackers like the Promodayz Virus typically have components that help them to reinstall themselves in the system again and again, and if those components are not detected and carefully removed, the web browser will be constantly taken over by aggressive online commercials.

Fortunately, our “How to remove” team has come up with a full removal guide that explains how to detect and remove the components related to Promodayz and if you are interested in it, you can check it out right below this article. To those wishing to easily reset their browser without wasting time, there is also a professional Promodayz removal tool for automatic assistance. Whichever method you choose to deal with the unwanted program, the best news is that this is not a virus and once you carefully get rid of it, your browser and your machine will operate like nothing has happened. Browser hijackers are not malicious pieces of software and they are unlikely to cause any long-lasting issues on the computer. However, oftentimes ransomware, spyware and other viruses may find their way inside the system thanks to the randomly displayed ads and web links that the hijacker can display on your screen. That’s why it is typically not advisable to keep such software for long and to let it expose you to questionable web offers, redirect links and sketchy banners.
