Malicious Domain Request is a potentially unwanted application (PUA) that “invades” computers through software bundling and automatic installers and replaces the settings (homepage, search engine, toolgar, etc) in the main browser with its own custom ones. The purpose of this application is to expose you to as many ads and page redirects as possible. Generally, Malicious Domain Request looks like a regular browser extension, which promises to provide you with some free functionality. In reality, however, this app behaves like a browser hijacker that uses aggressive marketing strategies to earn pay-per-click revenue. Let’s explain to you exactly this it works. When the application gets installed on your system, it immediately alters the settings of your default browsing program (it doesn’t matter if you are using Chrome, Firefox, Internet Explorer or another one). Changes may appear in your preferred homepage domain or search engine- in fact, both of those browser components may get replaced with some sponsored custom ones. You may also notice that every time you search for something on the web, different ads, pop-ups, banners and automatic page-redirect links may start to appear on your screen.

In case that you already have Malicious Domain Request on your PC, our advice is to be careful and to not click on its ads. Otherwise, you may be confronted with a sudden redirect to a third-party webpage, which may be sponsoring different unreliable products or services. There is no need to say that some third-party web pages may also be compromised and even dangerous. Therefore, it’s better to not visit them at all if you want to keep away from nasty threats like Ransomware, Trojans and other hidden viruses. In fact, most security specialists strongly recommend NOT to trust the content that browser hijackers such as Malicious Domain Request may display and to use reliable methods to have their changes uninstalled and their ads removed.

Tell us in the comments if any results came up when you searched for Malicious Domain Request in your PC’s Registry.

For this step, you will have to open your Start Menu and copy-paste the following lines, one by one:

  • %AppData%
  • %LocalAppData%
  • %ProgramData%
  • %WinDir%
  • %Temp%

Hit Enter after each one to open a file directory. In the directories, delete the most recent entries that you find there. In the Temp folder, delete all files.

In order to be fully sure that the unwanted software has been removed from your machine, you can also try using a Restore Point to roll back your system its last stable configuration. However, in order to do that, you would have to previously had had a restore point created. On most systems, such points get created automatically but this isn’t always the case.

The annoying application can often be added to a free application bundle and distributed through it.

Uncheck anything that is not related to the main application that you want to install and leave behind any potentially unwanted applications.
