What is Web Companion?

web companion program interface

Web Companion is a barrier between your browser and harmful websites and safeguards your browser’s settings against unauthorized changes. Ad-Aware Web Companion compliments your antivirus and browser’s defense against the most recent and potent malware.

Software development company Adaware, formerly Lavasoft, produces spyware and virus protection tools, including Adaware Web Companion.  Additionally, they created Lavasoft Digital Lock, Adaware Ad Block, Adaware File Shredder, Lavasoft Registry Tuner, and Lavasoft Privacy Toolbox. Solaria Fund acquired Lavasoft in January 2011.

They allegedly sold a starter edition of Lavasoft’s Security Program before their eventual purchase of the business. Examples of programs that alter web browsers without the user’s consent include the Lavasoft Web and the K-Lite Codec PackCompanion.

Does it get installed without our knowledge?

There’s a considerable likelihood the application got downloaded and installed without your knowledge if you’re searching for it online. This is due to the “Web Companion” program installing itself on your system without your consent and being bundled with additional software that you might not have intentionally downloaded. 

Although it is claimed that the companion guards against viruses and malware, there isn’t much that sets it from malware, the program alters some internet settings without the user’s awareness. It doesn’t benefit the computer’s performance.

It is classified as a possibly undesirable program due to how its creators distribute it (PUP). Users typically install these apps without knowledge, allowing the software to change browser settings. 

The official website offers a download for Web Companion. However, consumers frequently install it by mistake. This is due to the “bundling” strategy used by software developers. 

Bundling misleads users into installing potentially unwanted programs/ apps and other software. Developers frequently conceal these apps in “Custom,” “Advanced,” and other corresponding downloading or installation setup settings/options. The integration of these PUPs into installations is not fully disclosed information.

They are easily missed, especially if the download and installation processes are skipped and all other settings are left alone.

How to know if Web companion is installed?

After installation, Adaware Web Companion can be extremely annoying and pose a serious threat. The program will display pop-ups claiming to defend against the following dangers:

  • Invasive advertisements
  • Shady websites
  • Ponzi schemes
  • tracking of data

You can see a barrage of alerts whenever you switch on your pc because these cautions don’t have an expiration date for the windows service. Due to its constant appearance, it significantly degrades customers’ browsing experiences.

Unfortunately, the infection check results and supplemental advertising provided by the application are fake.

Is Adaware/ Lavasoft safe?

adware lavasoft program interface

Adaware, there are several reasons why Web Companion is risky.

  1.  Web Companion, an online security application, uses the outdated HTTP extension on its official website. It does not possess any HTTPS certificates.
  2. This outdated extension is marked as “not secure” by most browsers, including Google Chrome. The software probably lacks the funding necessary to develop better secure encryption techniques because it is a free utility.
  3.  Browser hijacking is an additional problem experienced by Web Companion users. Bing will take over as your primary web browser after you install it.
  4. If you successfully replace your old browser the first time, the web companion will keep asking you to change the settings until it gives up after the third attempt. 
  5. Before the Superfish incident, Lavasoft was reported for using Komodia SSL Digester in the Web Companion application.
  6. Experts claim that Komodia SSL Digestor compromises the security of your browser. Decoding protected web pages and inserting advertisements into them is its goal.
  7.  The most worrying aspect of Web Companion is that, according to its policy, Lavasoft can give users’ “non-personal” data to other parties.
  8. After Web Companion has been installed on your browser, everything you post on open platforms cannot be verified as secure or private. As previously mentioned, the program’s parent company, affiliate companies, and other parties may receive access to your personal information. 
  9. Lavasoft may compile information about your operating system according to the End-User License Agreement for Web Companion (release, bit architecture, version, etc.). It can conflict with installed apps. Additionally, it can negatively affect your Windows’ IP and services.
  10.  The most important caution is that if you already use a reliable security tool, like Malwarebytes, it will quickly identify the application.  It is recognized as follows by a wide variety of security devices: PUFF.WebCompanion!, 8.9E98, Riskware/WebCompanion, A Different Version Of MSIL/WebCompanion.C Potentially PUA CJ generic (PUA).

Therefore, it is advised that you purchase reliable software to secure the safety of your PC. You can successfully fish out fake programs like these in this manner.

How can one prevent the installation of a web companion?

  • Check all “Advanced,” “Custom,” and similar settings/options before downloading or installing software, deselect (opt-out of) any unwanted apps, and then finish the process.
  • Avoid third-party downloaders, torrents, and illegitimate or dubious sources when downloading software.
  • Use only direct links and authorized websites. Because cybercriminals spend lots of funds on ad design, even the most offensive adverts will look legitimate.
  • However, when clicked, they frequently lead to shady or dubious websites like those that feature adult dating, gambling, or pornography. 
  • If you encounter these referrals or the advertising that produces them, check your browser for any harmful extensions, add-ons, or plug-ins.
  • Check out the list of installed programs on your system as well. Unwanted or questionable entries should be deleted.
  • The ways to remove PUPs are provided in the next section if your machine is already afflicted.
