Web Companion removal instructions
What is Web Companion?
Developed by Adaware (previously known as Lavasoft), the Web Companion application is antivirus-type software designed to protect computers from malware infections and privacy breaches. In fact, it is categorized as a potentially unwanted application (PUA) due to the way developers distribute it. Apps of this type are often installed by users inadvertently, thus allowing the software to make changes to browser settings.
During installation of Web Companion, the installer demands permission to make changes to browser settings. Many users skip software installation steps and agree to everything, unaware of the risks. At time of research, Web Companion's installer promoted the Bing, Yandex, and Yahoo search engines. Therefore, giving permission to change browser settings will result in the default search engine, new tab URL, and homepage options being assigned to one of these websites. As mentioned above, this app is classified as a PUA, since developers promote it using deceptive methods such as "bundling". Therefore, it is often installed unintentionally. Do not trust applications distributed using deceptive methods. Although Web Companion is not a malicious program, many PUAs are distributed in packs that might include adware and browser hijackers.

Many apps are distributed using "bundling" and other similar methods. Examples include Lowe Registry Cleaner, Power PC Care 2018, and Advance PC Protector. Generally, these apps are promoted as providing 'useful' tools, features, and so on, however, few provide the functionality promised. Most cause problems and diminish browsing quality, cause unwanted redirects, deliver ads, etc.
How did potentially unwanted applications install on my computer?
The official website can be used to download Web Companion, however, if it was installed unintentionally, this probably happened when software developers employed the "bundling" method (mentioned above). Bundling is a deceptive marketing method used to trick people into installing potentially unwanted apps together with other software. Developers hide these apps in "Custom", "Advanced", and other similar settings/options of the download or installation set-ups. Information about the inclusion of PUAs within set-ups is not properly disclosed. They can easily go unnoticed, especially if the installation/download steps are skipped and all settings left unchanged.
How to avoid installation of potentially unwanted applications?
When installing or downloading software, check all "Advanced", "Custom" and other similar settings/options, deselect (opt-out of) unwanted applications and only then finish the download/installation process. Avoid using third party software downloaders, torrents or other peer-to-peer networks, and unofficial or/and untrustworthy sources to download software. Use only official channels (websites) and direct links. Bear in mind that cyber criminals invest time and money into ad design and, therefore, most intrusive advertisements will seem legitimate. Once clicked, however, they often redirect to unwanted/untrustworthy websites such as pornography, gambling, adult dating, and so on. If you experience these redirects, or ads that cause them, check for unwanted extensions, add-ons, and plug-ins installed on your browser. Also check the list of installed programs on your computer. Remove any suspicious/unwanted entries. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
