I am new to this forum at bleepingcomputers. ( I had trouble posting my introduction, which indicates my experience level with using forums, etc.)

My wife telecommutes for work. Her company's IT guy has left it up to us to fend for ourselves. He also telecommutes.

It has been determined that my wifes work PC is infected by spysheriff d. This was determined by running AVG antivurus software, yet the AVG could not kill it. PCTOOLS Internet Security 2008 did not even detect it. Wikipedia's info on the virus matches exactly what effect it has on my wife' PC. These symptoms include task manager is locked, system restore incapacitated, internet connection blocked, blue desktop wallpaper with spyware alerts in yellow, Wikipedia indicated that Hijackthis or SmitFraudFix may kill it. My boss who is not a master IT guy but does all of his own IT at the office, ran Hijackthis and SmitFraudFix and they did not kill it. Both pieces of software advise that a qualified user run these. I am not sure if he was fully confident in what he was doing and may have not done anything. The PC can not be run in the safe mode because her username and password do not work. This may be from the fact that this PC was aquired through a merger and the old IT staff can not be contacted to get any PC info. Can this get any better?

The end result is the PC is still infected. Reviewing Wikipedia's info on spysherriff indicates that Ad-Aware or Vundo-Fix will remove components of this virus. Does anyone know if this is true.

My question is does anyone know of a fix that I could be walked through. I am a user only but not stupid. I have rudimentary knowledge of PCs and have no problem loading software, etc.

At this juncture any advise would be greatly appreciated.
Thanks. It was nice to meet everyone.

Welcome to BC rtddjr

Depending on the actual file that was flagged, the AVG detection could be a "false positive". See this discussion on Trojan Horse SpySheriff.D

If you suspect a file to be a false positive. Test the file at [virusscan.jotti.org] and if it is a false positive, archive (zip, arc, tar etc) the file using a password and email a copy to virus@grisoft.com with a brief description as well as the password you used to archive it with.

If it is a false positive, turn off heuristic scanning for the time being. When Grisoft adjusts the virus definitions you can turn it back on. If turning off Heuristics still doesn't allow access to the file while testing and emailing... disable the resident shield temporarily.

You may want to perform another scan.

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

  • Make sure you are connected to the Internet.
  • Double-click on Download_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 Acan" option is selected.
    • Then click on the Scan button.
  • The next screen will ask you 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 and you may be prompted to restart your computer. (see Note below)
  • 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 will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.
