BleepingComputer.com: 'system Monitor: Potentially Rootkit-masked Registry' Found In My Pc

I sent a request to Webroot to help me fix this thing and their first suggestion managed to quarantine it. But this malware reapeared and now it wont show up in the
quarantine box no matter how often Spysweeper detects it. Their second suggestion is using ComboFix but I'm relunctant to run that software on my PC. According to
what I've read, you need to be a IT professional to use it. So, any suggestions? P.S. this is my first post. Thanks.

Each security vendor uses their own naming conventions to identify various types of malware. Without knowing the specific file associated with the threat and its location (full file path), its difficult to determine exactly what has been detected or the nature of the infection.

If the detection is related to a startup entry like Run: [Microsoft System Monitor] system.exe, then you are dealing with a nasty backdoor Trojan infection.

If you're using Windows 2000/XP, please print out and follow these instructions: "How to use SDFix". <- for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"

• Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  
• When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  
• If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  
• Please copy and paste the contents of Report.txt in your next reply.
  
• Be sure to re-enable you anti-virus and and other security programs before connecting to the Internet.

Please download Malwarebytes Anti-Malware and save it to your desktop.

• Make sure you are connected to the Internet.
  
• Double-click on mbam-setup.exe to install the application.
  
• 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 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 and exit MBAM.

Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

To quietman7 : Thanks for the suggestions. I performed a scan with SDFix in safe mode and then used Malwarebytes in normal mode and none of them
found anything. So I didn't see the need to paste the contents of Report.txt . What's strange is that in Spysweeper, the System Monitor is detected in 'custom sweep mode' but
not in 'full sweep mode'. I even configured custom mode to sweep the same things that full mode sweeps. Custom sweep detects it and full sweep doesn't !!?? Still waiting a reply from
Webroot for this one.

That's good that the scans came back clean. You may be dealing with a "false positive". Webroot will have to confirm.
