Relevant Knowledge is a PUP that circulates on the Internet since 2015

Illustrating Relevant Knowledge virus

Relevant Knowledge is a suspicious misleading software utility developed by TMGR Inc, which is classified as “adware” and “potentially unwanted program” (PUP).[1] 16 AV engines out of 48 recognized it as malware and prohibited its installation into a target system. In most of the cases, it is detected as Skodna.Generic_r and UnclassifiedMalware. Nevertheless, it's not malicious. All it can do is to enter the system without asking for its user's permission and then initiate marketing-related activities within web browsers. 

No matter that Relevant Knowledge software developers claim that the tool can help you to improve browsing on the Internet, that a psychological strategy used to increase users' rate:

RelevantKnowledge is an online market research community consisting of over 2 million members worldwide, which provides insight into how its members interact with the Internet. In exchange for agreement to have their Internet behavior monitored, computer users who join RelevantKnowledge are offered various value propositions, including the ability to download screensavers or other software offerings, entry into sweepstakes, and a host of other benefits

NoVirus.uk[2] team claim that Relevant Knowledge malware has been developed for affiliate marketing. It means that it's task is to promote programs, services, websites, products or whatnot that belong to affiliated partners. Therefore, regardless of the fact whether the PC's user installed it intentionally or got tricked into installing it via freeware bundle, it will install browser's add-ons, tracking cookies, and tracking pixels. 

Initially, relevant knowledge virus can activate tracking cookies and pixels. These small spying tools allow third-parties to monitor people's web browsing activities and collect information, such as IP address, email address, approximate geographical location, user's name, and so on. Usually, the Search Data is transferred to Google Analytics. However, it may also be sold on the black market and used for shady activities, such as malspam campaigns. 

How to remove Relevant Knowledge tmrg turned out to be one of the most commonly entered search queries related to this tool. It indicates the fact that people are not satisfied with the service it provides and we can explain why. As soon as its developers gather sufficient amount of information to understand your web browsing habits, they use 
RelevantKnowledge virus to generate misleading pop-ups and other types of ads. Some of them may belong to TMGR company, but the bulk is generated by affiliated third-parties whose intentions are not clear. By clicking on any of those ads, you may be redirected to suspicious and untrustworthy third-party websites.[3]

As you can see, there are many negative things that are related to this program. That's why we want to recommend you to avoid Relevant Knowledge adware by not installing free apps recklessly. If, however, it managed to trick you and hijacked your web browser, do not delay its removal. The longer you keep it active, the bigger is the chance to land on a compromised website or click on an infected pop-up. Yes, you can remove Relevant Knowledge manually. Easy manual removal tutorial provided at the end of this article will help you to do so. 

Nevertheless, we would recommend you to uninstall relevant knowledge with the help of a reputable security tool. Out top pick tools are Reimage or Malwarebytes MalwarebytesCombo Cleaner, but you are free to choose any other powerful, and necessarily updated, anti-malware tool developed by the reputable vendor. 

PUPs use a catch: hide under Quick and Basic installation methods

Although PUPs ask for user's permission to install on a target system,  they do this indirectly. Installers of unwanted browser add-ons, plug-ins, toolbars or extensions are usually hidden under Quick or Basic installation methods. Therefore, if you don't want to become a victim, you should start monitoring installation of the freeware.

Otherwise, you may become a potential victim of this adware and soon receive a message asking you to fill in some answers and so on. To prevent misleading ads and redirects that happen after clicking on them, you should start checking every freeware before its installation. Look at its Privacy Policy and End User's License Agreement and similar information.

In addition, make sure you select Custom or Advanced installation of the freeware and then carefully monitor every installation step. You should remove all check marks claiming that you agree with the installation of relevant knowledge 32 bit version. Otherwise, you may start suffering from pop-up ‘surveys’ and other pop-up ads that may try to redirect you to unknown websites.

This tool is ad-supported and programmed to initiate various marketing campaigns, including data collection, distribution of misleading online surveys or traffic increment to shady online shops.
