I did a deep scan with Norton Power Eraser (NPE) and it found this file, “rikvm_ C6F09094.sys” and reported it as “bad”. However NPE doesn’t or can’t erase it. I also attempted erasing it using NPE on a USB boot drive. It did not find it, but running NPE from Win7 finds it everytime, recommends erasing it (fixing it) but doesn’t erase it. It keeps showing up.

Here is what NPE says about “rikvm_ C6F09094.sys” :

FILE INSIGHT
rikvm_ C6F09094.sys found in (but not visible): \Windows\system32\Drivers
Reputation Details

Signature: Not Available, UNKNOWN Number of users in the Norton Community that have used this file: Unknown

Installed: Not Available, UNKNOWN This file release is currently not known.

Startup Item: No UNKNOWN There are no indications about this file.

Threat Details > (missed it, it may have said UNKNOWN too)

Should I worry about this file?

Hi MarkMagruder,

:welcome: to BleepingComputer.
We sincerely apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

Do you still need help? If so, continue to follow these instructions:

My name is Jason and I'll be helping you with your computer problems. You can call me by my screename jntkwx or Jason is fine.

Some things to remember while we are working together.

  • Do not run any other tool untill instructed to do so!
  • Please do not attach logs or put logs in code boxes.
  • Tell me about any problems that have occurred during the fix.
  • Tell me of any other symptoms you may be having as these can also help.
  • Do not run anything while running a fix.
  • If you don't understand a step, please ask for clarification before continuing with any future steps.

Click on the Watch Topic button and select Immediate Notification and click on proceed, this will help you to get notified faster when I have replied and make the cleaning process faster.

Note to others: The instructions here are intended for the person who began this topic. If you need help, please create your own topic in the appropriate forum.

 

:step1: Please download MiniToolBox and run it.

Checkmark following boxes:
  • Report IE Proxy Settings
  • Report FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List last 10 Event Viewer Log Errors
  • List Installed Programs
  • List Users, Partitions and Memory size
Click Go . Please put code boxes around just this entire log, like this, but without the letter x: [xcode] MiniToolBox log [/xcode]

:step2: 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.

  • 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.

IMPORTANT! If for some reason GMER refuses to run, try again.
If it still fails, try to UN-check "Devices" in right pane.
If still no joy, try to run it from Safe Mode.


In your next reply, please include:
  • MiniToolBox log
  • GMER log
  • How's your computer running now?

Regards,
Jason
