Good day.
Recently, many free programs are distributed with various add-ons: from "harmless" embedded advertising banners to various "spies" that collect information about your work.
RelevantKnowledge - This application is installed on your system, usually along with other small free programs. Then it collects information about your work and sends it to the site of the same name. Allegedly, in this way a new image of the Internet will be formed (on the one hand, the intention is not bad, but there is a big "BUT") ...
Why it is very suspicious: 1. RelevantKnowledge is installed without user demand (like a typical virus); 2. it is not known what kind of data it collects, what it analyzes and what it sends; 3. Despite the fact that the RelevantKnowledge icon is lit in the tray, this application cannot be closed. Even these signs are enough to "call" this application a typical spyware. I do not recommend that you leave it on the system ...
Now about deleting it ...

How to remove RelevantKnowledge
Method number 1
If you try to click on its icon in the tray (the screenshot below shows a typical icon for this application), then you will not be able to close it or delete it. All you will see (possibly) is an open page in the browser with information about the RelevantKnowledge description. Not much...
RelevantKnowledge
1) First you need to close this application and its processes. To do this, open Task Manager (keyboard shortcut Ctrl + Shift + Esc) and close all processes (applications) "Relevant-Knowledge" (also pay attention to the processes "rlvkng.exe" and "rlvkng64.exe" (on your system their names may be slightly different)).
Remove task
2) Next, open the Control Panel section "Programs and Features": find RelevantKnowledge in the list of installed applications and uninstall it.
Addition! To completely remove any application on your system, it is best to use the special. the Iobit Uninstaller utility. More about it here: //ocomp.info/ne-udalyaetsya-programma.html
Removing a program
3) Then restart your computer. Next, open the explorer and find the folder " C: \ Program Files \ Relevantknowledge ". Delete all the files in this folder, and then the folder itself. In general, after that you can be relatively calm about the system (Isn't it superfluous to check the work of the antivirus if you had one and "missed" RelevantKnowledge) .
Note: sometimes Windows reports that it cannot delete some DLLs from this folder. In this case, use the special. program for removing blocked files: //ocomp.info/kak-udalit-fayl-ili-papku-esli-ne-udalyayutsya.html
Method number 2
There is a utility like AdwCleaner... She specializes in removing ads, various browser virus add-ons, trojans, spyware, etc. What is especially captivating is that all that is required of you is to launch the utility and click scan (then it will do everything by itself).

As for RelevantKnowledge, it easily finds it and considers it a Trojan (which is not surprising in general). After scanning, the utility will offer to view the report on the found "infection" or go straight to cleaning (note: to do this, click on the "Clean and Restore" button) .
After that, this "virus" will be removed, the computer will be restarted, and you will see a report on the work done.

PS
1) After removing various kinds of "infection" from the system, I recommend optimizing and removing all the "garbage" (various temporary files, erroneous paths in the registry, empty directories, etc.). You can find out about the best automatic utilities for cleaning the system here: //ocomp.info/programmyi-dlya-ochistki-windows-10-na-russkom.html
2) I would also recommend from time to time to double-check the work of your regular antivirus using online products. (note: it is enough to download and run them. Fast and convenient!) ... I talked about the best of them in this article: //ocomp.info/onlayn-antivirusyi.html

Do not disregard various suspicious programs in the system!
Happy work!
