The most common symptoms of an infection with the Relevant Knowledge “virus” are the following – you might think that your browser has gone crazy because it is literally showering you with a great number of ads. What’s even more irritating is the fact that those ads do not resemble the typical ones. They may be very hard to close, they may automatically redirect you to pages with probably suspicious content. Such advertisements may even constantly reappear and an attempt on closing one of them may only lead to the opening of another. If this short description fits your recent technical issues, you could be trying to figure out what exactly is going on with your computer. The information you are going to read will make the current situation with your system clearer to you. We have provided some useful advice that can guide you through the uninstallation of this annoyance.

The RelevantKnowledge Virus

RelevantKnowledge is according to its developers “not a virus, spyware; it is not malicious or harmful to your computer.” However, most users would disagree and label RelevantKnowledge a virus – it exhibits the classical traits of an adware app – unwanted pop-ups advertisements.

If you have come across this article, you have probably already suffered from one of the most widely spread Internet nightmares – Adware. Maybe you are trying to remove the RelevantKnowledge virus  – one particular Adware application.

As the number of infections that are related to Adware-like products is constantly growing, more and more people become personally acquainted with this problem. Adware is the name used for the type of software, which has been created in order to generate advertisements of different products to groups of people according to their personal search requests. In fact, as you may have already noticed, even its name is derived from the phrase “advertisement software”, which implies that ads are likely to be involved. This advertisement-based software is what makes your system generate plenty of pop-up windows, banners and additional tabs on your browser (it doesn’t really matter whether you use Firefox, Chrome or Explorer).

The Relevant Knowledge App

Relevant Knowledge by TMRG is a survey app developed to analyze user’s online experience. The Relevant Knowledge app is a classic example of an adware-like product that will often display pop-up advertisements.

It will supposedly not share this information with third parties, but can we be really sure?

The aforementioned ads in various forms could promote all kinds of different products, webpages, and services.

Please, note that Adware hasn’t been identified as malicious as computer viruses as ransomware is. Malware, as in viruses and ransomware, destroys data, holds it hostage or “just” spies on you. In comparison Adware just displays ads. Most people find it annoying, also because of the methods, it may use to infiltrate your system. Such a scenario normally happens in different ways – when you download and install a software bundle from the web; or when you click on an advertising banner/link/line on a suspicious website. A software bundle is defined as a program that you download for free from the web. However, such products are often mixed together with other programs like Adware that get installed stealthily and you may not need on your machine. Despite all of this many security experts consider Relevant Knowledge malware.

Those are the most common ways it exploits to become a part of your system. Then it may surprise you with a lot of potentially useless and unwanted advertisements. Most Adware-based applications behave in a similar way because generating ads and promoting a product or service can accumulate huge profits for whoever exploits and creates such advertisement software. This is a completely legal marketing strategy, as long as you are not on the receiving end.

It’s important for you to know that Adware cannot damage your machine on its own. It might simply redirect you to suspicious advertising campaigns of possibly useless stuff. What’s more, it might even redirect you to pages with probably dangerous content, or ask you to download bad-quality software. Nevertheless, it is not a virus or malware itself. However, it does have some questionable features that may involve tracking your browsing history and movements on the Internet and selling that data to 3rd parties (vendors who are likely to want to sell you something).

What is Relevant Knowledge?

Relevant Knowledge is an example of an Adware product. Once Relevant Knowledge has entered your system, a lot of pop-ups or banners asking you to buy something or download something may begin to show up on your computer screen, while you are browsing the web.

Relevant Knowledge may be considered quite privacy-intrusive because the ads it generates could appear in a likely to be an aggressive way without your approval, wherever you go on the Internet. In fact, their number may be so big that your RAM might get stuck with them thus making the entire performance of your system more sluggish.

Useful tips on how to avoid Relevant Knowledge

The good news is that you can always avoid Relevant Knowledge and other versions of Adware just by following some simple steps:

  • It is important that your Firewall should be turned on and up-to-date. It will help a lot to prevent you from catching PUP (potentially unwanted programs), Adware or malware;
  • Purchase an anti-malware tool with a good reputation. If you choose a reliable program to defend your system, you won’t have any problems;
  • Download, purchase and install software only if it comes from trustworthy sources;
  • In case you want to install any software product, make an effort to always select the “Customized/Manual” Installation option. Read through all the agreements and do not authorize any changes to your computer as a whole or to your browsers in particular;
