Issue: How to uninstall Web Companion?

I was caught in bundling trick as by installing another free app I ended up installing Web Companion. The worst part is that I cannot uninstall it regularly. I opened Control Panel and tried to uninstall that program, but the pop-up occurred saying that Web Companion crashed. This happens again and again.

Solved Answer

Web Companion is a security program developed by Adaware, formerly known as Lavasoft.[1] It's not a primary antivirus program, though it's often classified as a second option antivirus or malware scanner. It's developer aimed at protecting people's PCs and data stored on them by anti-virus-level security features combined in the all-in-one app.

Ad-Aware Web Companion is compatible with most of the Microsoft Windows versions, including 7, 8, 8.1 and 10. Once installed, it adds an extra layer of security to boost web browser's defense in particular. The application blocks unauthorized changes to browser's settings so-called browser hijacking,[2] and hinder redirects to malicious websites. Its main advantage is that it fights against virus and malware at the URL level and immunizes it before it infects the targeted system.

However, many people have already created threads on IT-related forums asking for help to remove Web Companion. Such questions induced us to check what's the problem with the application so that it's objectionable.

Web Companion removal

We found out that this application is often dubbed as Ad-Aware Web Companion virus despite being legitimate because it initiates web browser's changes without asking for permission explicitly. Isn't it a paradox?

During the installation setup, the app contains a couple of statements saying that the user automatically gives permission to replace start page and search engine by installing this app. Such claims are marked by default and are approved as soon as PC's owner clicks Next.

Illustrating Web Companion distribution by bundling

Apart from the stealthy installation of web browser's extensions, the program subsequently resists the removal. It's not yet clear why people are not allowed to uninstall Web Companion, but that can be induced by potentially malicious files, browser helper objects (BHO),[3] and similar components.

Thus, if you installed Web Companion by Lavasoft accidentally or (intentionally) and cannot eliminate it, you should install Reimageor Perfect Uninstaller and run a scan, or follow manual Web Companion removal instructions given below.

  • Save the file as fixlist.txt on the desktop.
  • Now close all programs that are currently running and start the FRST file.
  • Click Fix button and wait until a Fixlog.txt file is created on the desktop.

According to many people, the culprit of the issue is Spigot adware or similar malware. Thus, if you cannot get rid of this application anyway, we would recommend you to boot the system into Safe Mode with Networking and run an in-depth system's scan with Reimage.
