RelevantKnowledge Description

RelevantKnowledge Screenshot 1RelevantKnowledge is a Netherlands-originating combination of spyware and adware, justified under the pretense of being useful for survey-related purposes. Just having RelevantKnowledge on your system opens up significant security risks and privacy issues, so it’s not recommended that you put your trust in this program. An additional warning sign is that RelevantKnowledge may be difficult to remove and may require anti-malware procedures to actually uninstall.

RelevantKnowledge’s Friendly Facade

Also known by Relevant Knowledge, RelevantKnowledge initially installs itself in a deceptive manner. This starts off with a pop-up imitating a standard Windows message when you visit an unsafe website. This pop-up, unlike most, tries to pass itself off as a simple and harmlessly anonymous survey. Actually trusting the pop-up ‘survey’ will cause the RelevantKnowledge spyware to be installed.

RelevantKnowledge will continue to try to play the part of a friend, with readily visible removal options and a theoretical justification for being on your computer. If you try to remove RelevantKnowledge, you’ll find that the options for uninstalling it are all nonfunctional!

The Relevant Dangers of RelevantKnowledge

While RelevantKnowledge’s on your system, you’ll experience obvious problems as well as more subtle risks.

The adware side of RelevantKnowledge will be plain, as it will bombard the user with unwanted advertisements with no easy way of being completely rid of them. Many pop-ups will continue the pretense of being survey-related, but they should be considered malicious in nature, given the deceitful and invasive nature of this program.

The RelevantKnowledge program is also capable of recording information and sending it to third parties. This is, once again, justified as being part of a survey process. Given that RelevantKnowledge doesn’t tell you exactly what information it logs and transmits, or offer options for opting out easily, there’s nothing to differentiate RelevantKnowledge from common spyware.

A Sneaky Bit of Malware to Catch

RelevantKnowledge may not be recognized by many different security programs, possible due to its dissimilarity to pre-existing malware. A surprising amount of otherwise high-quality anti-malware scanners have been reported to fail at catching it even years after its appearance! Keeping your scanners up-to-date, running them in Safe Mode, and using multiple scanners from different high-quality brands will increase your chances of removing RelevantKnowledge successfully. On the bright side, RelevantKnowledge is unusual in that it can sometimes be removed manually through the Control Panel, once the spyware’s process has been shut down.

Deleting RelevantKnowledge will prevent further harm from coming to your computer, but it won’t stop the damage that’s already been done. Once you notice it on your system, make removing RelevantKnowledge an act of high precedence, unless you like the idea of your computer’s information being freely shared out to the world!

  • Mark Corrothuers says:

    Truly good site thank you so much for removing relevantknowledge.

  • jonejan98 says:

    I have seen people complaining about it but honestly speaking it\’s not a virus. The software is used to measure online activity. I also thought it to be a virus initially but then found their website I did not have any problem in uninstalling it.

  • Larry says:

    Both Revo and regedit took care of it. I’m thinking I got mine from a site named, I got a Christmas card from a ‘friend’ was skeptical from the get go, but figured WTH, I assumed I too caught everything on the install, I always opt for advanced install because of tool bars and all. The riversong card was loaded with crap. Be Aware

  • Adhit says:

    only thing left for me to do now is find the CEO of the company let him get raped by 7’2" blackman, throw him in a cage with hungry lions, and chop his head off.

  • justin says:

    hi. i manage to find the relevantknowledge folder and i deleted it. but i think that the program is still somewhere in my computer as google ads get replace by some chinese girl thing. please advice!

  • Logic Computer Services says:

    how the hell did this crap get onto my machine!? I’m very angry

  • Jneinalsi says:

    This Is something interesting?


  • Nim says:

    A shorter way to remove it is (I’m not entirely sure if it removes all files so try this one first)that you go to Control panel then add or remove programs,find relevant knowledge and click Change/Remove.

  • iLLG8TE$ says:

    Your right Steve, Control Panel, Removal was successful for me too bro! I’m running Windows 7 too but, trust me, it’s still on ur comp! That is the 1st step that should be taken.

    (WINDOWS XP) >>>>START >>>> click RUN >>>> type in REGEDIT>
    (WINDOWS 98) >>>>START >>>> JUST KIDDIN! IF U HAVE WIN 98, Nuf Said haha

    >>> click from the menu bar EDIT>>>> type RELEVANTKNOWLEDGE (KEYS, VALUES AND DATA ARE ALL TO BE CHECKED MARKED FOR YOUR SEARCH) select/click FIND>>>> Everything with RELEVANTKNOWLEDGE will be searched and when it first finds RELEVANTKNOWLEDGE, it’ll be HIGHLIGHTED, just RIGHT CLICK>>> Select DELETE>>>> go back to EDIT>>> and select FIND NEXT (after you delete each file of course)——>>>>> Instead of going back to edit each and every time, it’s a lot easier to press F3 (FIND NEXT)>>>> Repeat steps until, REGISTRY SEARCH COMPLETED *****READ BELOW*****

    **For those of you that don’t know, when you’re searching for this stupid RELEVANTKNOWLEDGE, BEFORE YOU DELETE EACH FILE FROM THE REGISTRY, when the search finds a file, look/check to see what folder your deleting RELEVANTKNOWLEDGE from. My search turned up more than a couple RELEVANTKNOWLEDGE folders, therefore, I just moved my mouse over to the RELEVANTKNOWLEDGE folder and deleted the whole damn folder, then press F3. Or if u feel safer, after you run a search the first time, keep running & or repeating the search of your registry until nothing is found that is associated with (do i have to type it again you know?!! lol)>>>> Restart comp. Now do what “””Me Mhy”””” says (You can repeat the search in REGEDIT to double check, it’s gone, after comp restart..
    *****************IMPORTANT! If this is your first time running REGEDIT, be careful and double check before you delete anything from the registry*********************

  • Me Mhy says:

    I follow the Steps and Alhamdulillah it’s works well, but in my case what i’ve done is :
    1. I Remove all everything that relates with “RelevantKnowledge” in the registry, just use registry editor and use the “find” facilty, search by keyword “RelevantKnowledge”, search from the begining. if you have finish than repeat once again, make sure that RelevantKnowledge registry was removed all
    2. Restart your computer
    3. and last, use Step 1 : Use Windows File Search Tool to Find RelevantKnowledge Path, with the keyword “%ProgramFiles%\relevantknowledge” and delete the directory

  • steve biswanger says:

    Go to control panel/programs/RelevantKnowledge & delete. worked instantly with windows 7.

  • Anthony says:


    Thank you for your help with this issue, however I am unable to remove two .dll files associated with RelevantKnowledge, rlls.dll and rlxg.dll

    I have tried the regsvr32 /u [DLL_NAME] command, but I get a windows error message reading that the .dll was loaded, but the dllunregisterserver entry point was not found.

    I have typed everything correctly.

  • Randy says:

    Yeah, this crap installed itself without my permission. I’m very careful about unchecking options while installing programs so these spyware programs don’t get installed. This one just popped up and caused my games to crash. Once I noticed it, I removed it and all was fine. They have a lot of nerve to act like you requested the program.

  • xplunk says:

    I found that relevantknowledge did take up some processor resources. It slow down my notebook … Now already remove the application. Don’t know how this app installed in my notebook….

  • Andrew says:

    Hey nice tut but i dont get Step 5 : View the RelevantKnowledge Components with its MD5s.

    What is an MD5 and how do I delete it?

    And what is the difference between Step 2 and 4?

    Thank you for your help.

  • wintermute says:

    This application was responsible for freezing my Vista Ultimate x64 Desktop right after startup every time. It got – unwillingly and unwanted – installed side by side with puresync (a free synchronization software).
    I recommend removing this bad software immediately, It cost me 3 expensive hours to locate the problem by turning off service by service in msconfig in safe mode.

  • francois delgado says:

    i removed the virus before i went here my computer was slow and im a hacker so i checked my processes and i terminated they came back i repeated to terminate finally worked searched my program files and found relevant knowledge the i changed all to .txt files and deleted

  • John says:

    Found this bundled within Format Factory. When I declined the install, to my surprise McAfee came alive that it was trying to execute RKVERIFY.EXE.

    It is a shame that even when you DECLINE an install, it is still trying to load and execute the software bomb.

  • souweine says:

    I did find registry C:/program files/RelevantKnowledge, but couldn’t achieve step 2 of the procedure, because processes reappears as soon as I killed them.
    So I booted on command safe mode and killed by DOS command the four files present in relevantKnowledge folder.
    Is there an inconvenient or a danger to do so as, apparently, I get rid of the spyware ?
    Thanks so much,

  • Erkan says:

    i followed the steps but i couldn’t do fourth

    Step 4 : Detect and Delete Other RelevantKnowledge Files

    1. To open the Windows Command Prompt, go to Start > Run > type cmd and then press the “OK” button.
    2. Type in “dir /A name_of_the_folder” (for example, C:\Spyware-folder), which will display the folder’s content even the hidden files.
    3. To change directory, type in “cd name_of_the_folder”.
    4. Once you have the file you’re looking for type in “del name_of_the_file”.
    5. To delete a file in folder, type in “del name_of_the_file”.
    6. To delete the entire folder, type in “rmdir /S name_of_the_folder”.
    7. Select the “RelevantKnowledge” process and click on the “End Process” button to kill it.
    8. Remove the “RelevantKnowledge” processes files:

    i tried to use Windows Command Prompt but it says always that cannot find the directory… when i tried to delete the entire folder it asks for a yer or no when i say yes it againd says cannot find the directory… i am using windows defender antispyware program but is is not helping me…
