What is RelevantKnowledge

RelevantKnowledge is a rogue application categorized as adware. It is promoted as an “online market research community consisting of over 2 million members worldwide, which provides insight into how its members interact with the Internet”. RelevantKnowledge ostensibly improves browsing by displaying more relevant banners basing on users’ preferences. Although this service may seem useful, it is designed to collect anonymous browsing data and sell it to cybercriminals. When RelevantKnowledge is installed, it instantly changes browser settings in order to impose a multitude of ads displayed upon the content of pages. Such ads are more likely to contain redirects to adult websites, fake flash player updaters, freeware, and other malicious pages. To ensure that your data is protected, you should get rid of RelevantKnowledge right now!
