How to remove Defru (Virus Removal Guide)
What is Defru?
Defru is a potentially unwanted program (PUP) and potential malware found in the adware category of computer threats by many reputable security products. Defru is used to retrieve and gather user information, change existing internet browser settings, and serve advertisements on Google Chrome, Mozilla Firefox, and Microsoft Internet Explorer.
Possible Defru malware and associated programs, comprising additional browser add-ons and extensions often have permission to access and gain user information such as a user’s complete browsing activity and history, as well as information about bookmarks and browser themes. This information is used to serve targeted advertisements across different internet browsers and may also be put forward to third-party contractors (marketing and mailing lists).
Internet users may also encounter unwanted browser redirects when opening a new browser window, opening a new browser tab, or searching the web using the browser address or omni bar.
Advertisements shown by this program are delivered in many different forms and are often identified by text that says something similar to “Ads by Defru,” although these advertisements may be served by additional third-party adware and advertising platforms.
Defru has been found to relate with and package itself with additional third-party malware and PUPs during the installation process of third-party freeware endorsed by media related websites. In some situations a user may be presented with the opportunity to agree or refuse an offer to install this item and supplementary programs: However, the request to decline is often ignored.
