What is Web companion?

Web Companion is the security software that comes to your system uninvited

Web CompanionWeb companion is a potentially unwanted program which is claims to add an extra layer to your PC's security.

Web Companion is a legitimate application created by Lavasoft. According to developers, the program can add an extra layer of protection by blocking increasing the security of Google Chrome, Mozilla Firefox, Safari, or another web browser by blocking malicious websites.

Due to implemented protection, it can also prevent the infiltration of potentially unwanted programs installed as browser extensions via various websites. Ironically, the program itself is a potentially unwanted program, as it usually gets installed with shareware and freeware programs deceptively.

However, its distribution techniques are not the only questionable feature of Web Companion. The PUP actively pushes its paid version as the only way to evade issues that it detected. However, security experts, the Reddit community, and other respectable parties do not believe that it is worth spending your money on such a questionable tool.

The main problem related to the software is the methods used in its distribution. The developers have already admitted that their product is distributed via a popular marketing method called bundling[1]. They clearly identify in their FAQ section that the application might appear on the user's computer without direct permission and start operating on the system:

Web Companion is most commonly distributed within another software product that you or someone who uses your PC has elected to install. This is known as “bundled software distribution” and is a practice widely used by software makers worldwide to make money while delivering free software to their end-users.

While some users might question what is Adaware Web companion, others refer to this program as a virus. Security researchers indicate that this is not the right term to describe this software. It should be attributed to the potentially unwanted program category because of its stealthy techniques used to enter the system and also sell its licensed version.

IllustrationWeb companion is often described as a virus since it delivers annoying virus scan pop-ups.

Even if the application is installed willingly from its official website, its installer also offers a bunch of programs that can be considered browser hijackers. When users do not pay close attention to the installation of such software, they might not even notice that the permission to change web browser settings is being asked for with the help of pre-ticked boxes, fine print text, and other tricks.

Therefore, Adaware Web companion is installed, users might notice that their web browsers are suddenly redirecting search results to Yandex, Bing, Yahoo, or Privado and filling them with sponsored links and ads. These providers might also be set as default browser homepage and new tab.

Besides, users might also spot new extensions or new programs installed on your web browsers or Windows/Mac systems – these might secretly track your online activities and deliver this information to third-party sources for financial benefits.

The questionable activity of the Web Companion PUP

We should also add that program's activity can also be quite annoying and cause trouble when trying to uninstall this so-called system protection tool. Once installed program claims to protect against the following threats:

  • Rogue websites;
  • Invasive ads;
  • Data tracking;
  • Phishing scams[2].

However, users start receiving notifications about detected threats from the app right after the first scan is finished. Unfortunately, these alerts do not have an expiry date, so you can be flooded with never-ending messages each time you start using your computer. It has been significantly deteriorating users' browsing experience because it keeps popping up without a break.

Unfortunately, virus scan results and additional ads by Web companion are not necessarily trustworthy. Developers aim to generate revenue and try to trick people into believing that their computers are infected to continue using less than reliable services. In some cases, users might even be prompted to purchase the premium version or install additional security tools.

DetectionProgram is detected by various security vendors

Possibly the biggest red flag is that, if you are already using a reliable security tool such as Malwarebytes, it would immediately flag Web companion virus as a PUP. There are quite a few other security tools that detect it under the following names:[3]

  • Program.Unwanted.3914
  • PUA:Win32/Puasson.A!ml
  • A Variant Of MSIL/WebCompanion.C Potentially
  • Generic PUA CJ (PUA)
  • PUF.WebCompanion!8.9E98 (TFE:C:9RseB869T6O)
  • Riskware/WebCompanion

Therefore, we recommend you to get a trustworthy tool to maintain your computer's security. In addition, if you have been questioning yourself “should I remove Web companion from the system,” our answer is “yes, you should.” You can uninstall the app from Windows 7, Windows 10 or other Windows operating systems with the help of the step-by-step guide given below.

Manual removal doesn't take much time. However, run our recommended tools to make sure that there are no leftover files on the system. Keep in mind that such apps tend to modify the computer's registry and initiate additional modifications to start working with every system's startup. To revert these changes, we suggest using ReimageIntego.

People keep finding the app installed without their approval

The answer to the question of how did program got installed on my computer is more than simple — this security tool spreads in a bundle with third-party applications. In other terms, you install the software during the installation of free programs.


Even though this distribution technique is legitimate, users can fail to identify and reject programs they don't want to install. As a result, victims have started numerous discussions about the unexpected appearance of this tool on Reddit, Quora, Microsoft, and similar tech forums.[4][5]

How to prevent from getting system tools

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
