What is RelevantKnowledge?

RelevantKnowledge is advertised as “an online market research community consisting of over 2 million members worldwide, which provides insight into how its members interact with the Internet”. Though this may sound like a useful service, RelevantKnowledge can be intrusive and will display advertisements whether you want them to or not. To do this, the RelevantKnowledge adware uses either a browser extension or a program.

When it is installed, the RelevantKnowledge will display advertisements when you search on Google and on web sites that you visit. The RelevantKnowledge advertisements may have a different text under the pop-up: “Ads X”, “Powered by RelevantKnowledge”, “Advertisements by RelevantKnowledge”, “Brought to you by RelevantKnowledge”, “Ads by RelevantKnowledge” or “Ads powered by RelevantKnowledge”.
The RelevantKnowledge ads will typically be shown in the header in strange positions or overlaying the content of the web page. These RelevantKnowledge ads are for adult sites, online web games, fake software updates, and unwanted programs.

When the RelevantKnowledge browser hijacker is installed on a computer, common symptoms include:

RelevantKnowledge ads are displayed in the Google search results
Advertisements appear in places they shouldn’t be.
Website links redirect to sites different from what you expected.
Browser popups appear which recommend fake updates or other software.
Other unwanted programs might get installed without your knowledge.

How did RelevantKnowledge get on my computer?

RelevantKnowledge is installed by the users, whether that is knowingly or not. Often, this type of program is offered through advertisements or bundled with other software, leaving the user puzzled where this software came from.
Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed RelevantKnowledge without your knowledge.

You should always pay attention when installing software because often, a software installer includes optional installs. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.

Although HitmanPro is shareware and costs $24.95 for 1 year on 1 PC, there is actually no limit in scanning. The limitation only kicks in when there is a need to remove or quarantine detected malware by HitmanPro on your system and by then, you can activate the one time 30-days trial to enable the cleanup.

AdwCleaner is a free popular on-demand scanner which can detect and remove malware that even the most well-known anti-virus and anti-malware applications fail to find.
