I have Windows 7. From the moment I have had it, I installed the full Norton Security Suite.

I first suspected that something was wrong when I would click on a link, and I would be redirected to a different website. I did some research, and I read about some Google Redirect Virus. I don't know if that is what I have because lately I haven't been redirected to other sites.

What's affected is my browser (Firefox).. When I type the vertical dash line will freeze periodically, and if I type while it is frozen, the words that I type, even though they're correct, will appear like complete gibberish.

I did scans with Norton, and did a rootkit scan. It finds something with the name rikvm_C6F9094.sys. I tried to find it in the computer by searching, but it's not there. Norton says that it removes it, and it appears that for a moment the computer works. But then when I run a scan again, the same file shows up.

I downloaded Comodo, but it didn't find anything.

What is this rikvm file, and how do I delete it? I just bought this great laptop for school, and I desperately need it to work properly!

ALSO, since the computer is new, I decided to restart the computer from factory condition, and the problem has persisted regardless.

Hello,I moved this to the Am I Infected forum.

did a rootkit scan

. Was that with Norton?

lets run another tool. That file is a malware file and does need to be removed.


Next run Malwarebytes (MBAM):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Troubleshoot Malwarebytes' Anti-Malware

Please ask any needed questions,post logs and Let us know how the PC is running now.

Yes, the rootkit scan was done with Norton.

I did a quick scan that found nothing, and I did a full scan that also found nothing. I'll post the quick scan log:

Run TFC by OT (Temp File Cleaner)
Please download TFC by Old Timer and save it to your desktop.

Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.

If it finds something make sure Cure is selected

Now a rootkit scan
Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

I have very similar problem last night. norton internet security crashed and redirect me to use norton power eraser to scan.

And it kept telling me rikvm_38F51D56.sys is bad, after i removed and reboot. it's back again just like you.


However, i been searching and trace the root of problem to kmsvc.exe, it's from cyberlink power dvd, it's list under Service as "PowerLink Product".

once i disable the service, Norton Power Eraser can't find the file anymore.

I think It created some kind of dynamic driver in the MBR but disappeared after service stopped. Even i am 100% sure it's from CyberLink and not a virus, it's very weird why would cyberlink do something like this.

I have disabled the service from startup and the power dvd still working, i really have no idea what does kmsvc.exe / service do.

I suspect that it's some type of root kits to monitor user?

Writing to cyberlink was no luck, neither is their KB, couldn't find anything relate to the rikvmxxxxxxxx.sys nor kmsvc.exe.

I'm writing to confirm that the rikvm spyware/crimeware/virus is in fact from cyberlink power dvd, it's list under Service as "PowerLink Product". DO NOT DOWNLOAD THE UPDATE FOR THE CYBERLINK DVD! Once I removed the cyberlink power dvd update, the crimeware was permanently removed from my computer. Thanks for the tip. Thank God we were able to find the root of the problem.
