Web Companion Unwanted Application

Web Companion Unwanted Application

/ Shayne Sherman

What is a Web Companion?

Web Companion is an application developed by Adaware (previously called Lavasoft) that is designed to protect computer systems from malware infections and other privacy breaches. However, Ad-aware Web Companion is flagged as potentially unwanted software due to the way it was distributed by its developers.

Applications like this are often installed by users unknowingly or who don’t understand what they are actually doing.

In the installation process, the Adaware Web Companion software asks the user for permission to make changes to your browser. Most users don’t pay attention to this and just click the ‘Next’ and ‘Accept’ buttons mindlessly.

Additional Information About Lavasoft’s Web Companion

The installer for Web Companion asks for permission to modify the settings of your existing web the installer for Web Companion asks for permission to modify the settings of your existing web browser throughout the setup process. Many consumers ignore the program installation process and agree to Web Companion’s EULA or their terms and conditions, oblivious to the dangers. The Yahoo, Bing, and Yandex search engines were observed to be advertised by Web Companion’s installer during the time of this writing.

As a result of granting permission to modify the default web browser settings, one of these sites on the internet will be made as the default search engine, default website for new tabs, and the homepage options. As mentioned earlier, this program is categorized as a Potentially Unwanted Application since its creators use misleading marketing techniques such as “bundling” to advertise it. As a result, it is frequently installed unintentionally.

Although the program feature of Web Companion sounds good, we strongly suggest steering away from it because of its sketchy way of marketing associated programs.
