This file showed up in a list of commands in the Windows Task Manager (Ctrl+Alt+Del). I may not know which files are supposed to be active, but this one definitely caught my attention as something new/different. It's scary. Kaaizer

its a spyware using your full internet speed and its from AOL "delate it from regedit" HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run). rlvknlg.exe spy ware killer
This exe has somehow meshed in with my network config. When i try 2 quarantine it, my wireless adapter cant establish its dedicated IP. Can anyone post on how 2 remove? Nate
When i am on the internet no matter what browser i am using rlvknlkg.exe makes other processes use every bit of spare CPU power stop its process my computer runs almost normal i got it from downloading AIM
It is spyware. I discovered it in taskmanager because it came up whenever i logged on, and i didn't like the look of it, so i researched it. I kept ending the process, but that did not solve the problem. If you have windows xp, go into my docs, etc. and hit search, all files and folders,and type in rlvknlg. In advanced options, tick all boxes, and then search. it should come up with the file, and might have an icon displaying a computer with a red "M" on the screen. Delete it, and also remove it from your recycle bin. Luna
remove this if you have it john
there is almost no way to delete this file spyware programs dont find it or anything, but look how much it uses of your computers processing power Zach
to delet just find it in C:\windows\system32 then end its process in the processes window in windows task manager then drag the file into delet bin and it should go with out a problem =3 Matt Grudewicz
It's a pain to get rid of as killing it spawns 5 instances (on my machine anyway). Took a safe-mode reboot to finally get rid of the damned thing, then I had to fix my TCP/IP stack. Basiclife
for my opinion this file is dangerous its collecting some info so its a spyware and should be deleted Mike
Yes this file may well cripple the network (see link below) - its a network proxy. However this file may have ist own "add/remove programs" entry under "Relevant Knowledge"- in which case it can be safely removed that way.  See also: Link pete
I removed it from registry settings, killed the process and deleted the exe Greg
File was eating processor and locking internet explorer. Killed it okay from task manager. Found it in \windows\system32. In properties (right click) it identified itself as from Relevant Knowledge; deleting it did no harm to system. Couldn't find it listed in any of the startup places. pete

It stopped me from even launching any browser. This thing is bad for sure. I'm so glad that it was on my virtual machine. I removed it simply by going to add & remove programs Roger More
I found the relevant knowledge file in my program files folder. I deleted everything in the folder except for a rxlg.dll that won't allow it. how do I get rid of the dll? Also I can not find any evidence of relevant knowledge under run or runonce in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ orHKEY_LOCAL_CURRENT _USER\SOFTWARE\Microsoft\Windows\CurrentVersion\

Freezes Vista installations. Start in safe-mode and do a search for the executable (may take a while, like mine) and remove it. If you can't find it, google 'sysinternals autoruns' and download the program in the first result. Using it, try to find and remove the executable's entry. Good luck if you can't find it! Declan
Bad File, try to remove at all cost but be careful when editing the registry, I also found this at C:\Program Files\RelevantKnowledge\ Franco

Three months after you delete rvlknlg.exe, you can only use your laptop in safe mode or it will freeze at startup. CRAP! Beware: Norton 360 does not catch this virus. A.J.
Took me a while to get rid of it, i ended the process but soon realized that it would immediately start up again. I had to end the process about 20 times before i was able to delete the files Robert

This gobbles processor power. You cannot delete rlvknlg.exe while it is running and when I ended the process it would restart immediately before I could delete it. Found it in /Program Files/Relevant Knowledge so they don't try to hide it; it even put its icon in the task bar! However, I could rename it, then end the process, then delete it and everything else in the same folder except for a .dll file which is impossible to delete but I did rename it. Also searched for it in REGEDIT and deleted it there. All OK now. Richard Shorter
I got rid of it with fileassassin.  See also: Link Nick
It slows down my computer, eats my ram,and I can't end the process nor can I find the program in C:\windows or C:\Windows\system32 Negative.
It eats up a lot of CPU. My pc can take half a minute to read one keyboard stroke. Must remove it.
remove the virus manually. if using win7, then open up task manager and check the process. see f there is rls*** rlv** and an unsecapp process. right click on the rlv process and select open file location. move the folder to desktop, near the recycle bin for fast drag delete. now uninstall any torrent/illegal acquired program or a download from an unsafe website. then open resource monitor and suspend the three processes. and disable it. go to control panel and uninstall programs remove its directory.then delete it. it worked for me. s.a.m.
Can't delete .dll files. My fps in League of Legends is so low because of this. Computer is runing so slow Alex
Removed it by uninstalling Relevant Knowledge program V.F.
I found this on my computer when I opened Skype and it said "rlvknlg.exe" wanted to access my Skype. I clicked no and then went searching for the file and found out I had this Relevant Knowledge stuff on my computer. I removed it using add/remove programs and it worked. It didn't seem to do anything bad, not to my computer at least. Stormy
I uninstall it from Program & features of my win 7, rename the file, end the process, and viola! my pc is fast again Arief
hey, i somehow got this program 2 days ago and i know what speed my comp usually runs at so i opened up taskmanager processes and was constantly ending the process to no avail. After reading this i went to add/remove programs and the uninstall seemed to work fine *fingers crossed* and now i can tell a huge jump in speed, thanks for all the help! C.G.

I notice that some programs which should be easy to remove using uninstaller cannot be uninstalled because of other spyware on the computer that works behind the scenes. Free antispyware programs can be used to remove the spyware and the uninstall the genuine programs. One such example is relevant knowledge software that is a genuine program and is installed with user's permission but then sometimes become difficult to remove because of other spyware. Michal123
Relevantknowledge is not a virus. It is a genuine software. If you find it annoying, you can uninstall it from control panel. You can read more about this software on their website relevantknowledge.com  See also: Link Michal123
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 relevantknowledge.com. I did not have any problem in uninstalling it. jonejan98
Its deleting windows files and try to copy other peopple usually it try send him self on skype or on messenger or on some chat place and every time when you start windows it destroy files jani
It's spyware used by other companies to find out what you are looking at on the internet and the relevant knowledge people sell the information on what you're searching; in my view things that spy on what you look at without your permission should be illegal! Conor
I think spyware is not the right term becasuse software is installed with user's knowledge and permission and can be removed easily using uninstall program from the control panel. It's not malicious. It is just a program that gathers some information about user's browsing habits. It is a genuine piece of software. jonejan98
I got it on development VM with 0 new programs installation and 0 browsing, so it must use sort of worm/zero-day vulnerability spreading mechanism. Very bad. Howewer easy to destroy - rename "Program files/relevant knowledge" folder to "111". Reboot. Delete the folder. osty

goes in and sneaks on all your files and spreads adware everywhere. AVG reports it as a virus and it is located in more places than program files. can have detrimental effects on system. Dave
This is a rogue internet security virus. It runs on start up and can affect other files on your computer ex; firefox, this virus tracks information from internet browsers and is capable of sending passwords, credit card numbers, email addresses, and sites you visited to whoever wrote the virus or third parties. You should remove this immediately.  See also: Link Expert

Eats CPU usage, monitors your internet activity, slows watching online videos jeremy
I noticed my CPU usage was almost always nearly at 100% so I checked my running processes and I found it. I tried deleting it, but it came back. So I renamed it, stopped the process using task manager, and then deleted it. Deleting it reduced my average CPU usage all the way down to 30% and made my computer a LOT faster. I recommend deleting it as soon as possible. Oscar T.G.
This is an extrmemly dangerous program. G-effect
