Hi, i've got a computer here thats infected with adware.w32.spyshredder. I know its a fake virus to trick you into buying antivirus software, but I still cant get rid of it. I whent to this site http://vil.nai.com/vil/content/v_144189.htm#VirusInfo, and deleted these registry values:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
ctfmona: "%Windir%\system32\ctfmona.exe"

HKEY_CURRENT_USER\Control Panel\Desktop\SCRNSAVE.EXE: "%Windir%\system32\blackster.scr"

HKEY_CURRENT_USER\Control Panel\Desktop\OriginalWallpaper: "%Windir%\system32\ctfmonb.bmp"

HKEY_CURRENT_USER\Control Panel\Desktop\Wallpaper: "%Windir%\system32\ctfmonb.bmp"

but it still acted up. The fake virus desktop background was gone, but it still said it had a virus. The person who owns the computer installed an intivirus program the the malware suggested. I forgot the name but it ended in "control center", or something. The main problem is when I start the computer normaly it shuts down after it gets started and into the desktop, it shuts down windows explorer and locks up. I cant run HJT or run AVG which I installed while in safe mode. The computer shuts down before I get a chance. I also searced for the file ctfmona.exe in safe mode and got two hits, a .exe and some other one and I deleted them both but it still isnt working.

If someone could tell what to do, since this is sort of a unique situation where I cant run an antivirus program.

Thanks.

Please print out and follow the instructions for using "Vundofix". -- If using Windows Vista be sure to Run As Administrator.
  • Click the Scan for Vundo button.
  • Once it's done scanning, click the 'Fix Vundo' button.
  • After running VundoFix, a text file named vundofix.txt will automatically be saved to the root of the system drive, usually at C:\vundofix.txt.
  • Please copy & paste the contents of that text file into your next reply.
-- If you receive this error: "Run-time error '339': Component 'comdlg32.ocx' or one its dependencies not correctly registered: a file is missing or invalid", a new copy and instructions on where to put it can be found here.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.
  • 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 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.

Yeah, I dont think I can do that because the computer dosent stay on long enough to try that, it slow to start because the owner has about 4 IM programs set to run on start and when thats done, Windows Explorer shuts down and doesent come back. I cant cant even get the Task Manager up to end the IM programs on startup because it says its been disabled by the admin, I havent looked to see if I can enable it myself.

Anyway, will this program you showed me work in safe mode?

MBAM is designed to be at full power when malware is running so safe mode is not necessary when using it. However, if you need to you can use MBAM in safe mode. When done, then try running Vundofix in normal mode.

Another thing you can try is to disable the IM programs with with MSConfig.
  • Go to Start > Run and type: msconfig
  • Click "OK" and the System Configuration Utility will open.
  • Go to the Startup Tab, and uncheck those IM programs listed there.
