What is about:blank?

There are several reasons why your web browser might display an about:blank webpage. There could be a problem with your browser settings, your computer could be infected with adware or a browser hijacker that changed your settings, or you could be visiting a website that displayed a pop-up advertisement.

about:blank

The about:blank page is not malicious but it is something that needs to be addressed on your computer or the sign that you should avoid specific websites. Websites that usually display an about:blank webpage are known to utilize malicious advertising networks that display pop-up advertisements. Legitimate advertising networks do not produce pop-up advertisements. Websites that use an advertising network that displays the about:blank webpage often bolster malware, adware, spyware, and other malicious threats.

Adware and browser hijackers will also cause your browser to display a plain white and blank about:blank page. The browser hijackers modify browser settings and oftentimes will open up or redirect you to an about:blank page. Adware will typically display the about:blank page when it is attempting to generate a pop-up advertisement or failed to do so.

Browser hijackers will change the homepage, default search engine, and new tab URL to a new one. This will cause internet searches performed in the address bar to redirect to a new website. It will also cause affected browsers to start on a different website and redirect to the website when a new tab is opened.

How did about:blank infect my computer?

The about:blank webpage does not essentially infect computer systems. Adware, browser hijackers, and other malicious programs are known to download and install without user consent or knowledge. This is usually caused by a third-party download manager, third-party programs, or trojan downloader that has initially infected the computer.

Adware and browser hijackers that display the about:blank webpage are also sometimes offered as a custom installation by freeware and other content such as codecs, media players, download managers, and updates; However, the installation process typically does not allow the user to reject about:blank from installing and the program will install anyways.

It is important to avoid installing free programs online that offer this program as an installation because they are not usually safe to download themselves.
