How to remove rlvknlg.exe trojan

A ran into a computer running Vista SP1 that would freeze about 10 secs after it booted into windows.  I noticed that it froze after a wire framed globe would appear in the taskbar right as it froze.

It turns out that it was connected to a malware/spyware program called Relevant Knowledge.  It tracks online purchases.


Boot into SafeMode

  1. Restart your computer
  2. Press F8 repeatedly as your computer is booting up.
  3. You will be presented with Windows Advanced Boot Option, choose SafeMode using your arrow keys.
  4. Press Enter to boot into SafeMode
  5. The computer will bring you to the SafeMode login screen, login as usual.


Uninstall the Relevant Knowledge program

  1. Click on the start button
  2. In the Start Search field, type: Programs and Features and press enter.
  3. You will be presented with the Programs and Features Uninstall or Change a program screen.
  4. Find the entry for Relevant Knowledge and select it
  5. Click the Uninstall button at the top of the list.
  6. The program will uninstall.

At this point the program is uninstalled and you should reboot your computer.  However, it is a good idea to run a malware scan on your computer to make sure everything is cleaned out completely.  If this spyware/malware was installed on your computer, more than likely you have more unwanted spyware.  

Reboot you computer in SafeMode with Networking if you are going to proceed with the recommended options step below.

Thanks a lot!!

Good to have found some info on this at last.

The method I used below avoided restarting the computer.

I removed it (So far anyway!) by stopping the program in task manager (Control + Shift + Esc) under processes then uninstalling it via the normal windows ‘Uninstall’ routine.

I then scanned my PC with the free and popular Spybot program which found it and dealt with it. When I closed Spybot the system tray icon finally disappeared.

Thanks a lot! from Uruguay!

Wow, this is really usefull! Tnx a lot!
