tried using the removal instructions from this site and I get to downloading "Process Explorer" to dektop and then change name to explorer.exe but when i double click it doesn't run/open. This virus won't let me open anything from HD, USB flash or CD drive. I can access the internet but not run applications. Is there an updated version or a work around.

I'm about to the point of just wiping clean and reinstalling OS. If I do that do I just reinsall with original OS and driver discs or do I need to wipe hard drive first to get rid of virus.

Thanks

Hi stephenisr and :thumbsup: to BleepingComputer!

Lets see if we can get Malwarebytes Antimalware to work. If your infectec computer is preventing you from downloading it, use a flash drive, but make sure you use Flash Disinfector to make sure you do not infect another computer.

Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.


MALWAREBYTES ANTIMALWARE
-------------------------------------------
Please download Malwarebytes Anti-Malware and save it to your flashdrive (in case you are not able to download it direct to your infected computer). Rename mbam-setup.exe to winlogon.exe
alternate download link 1
alternate download link 2

MBAM 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 winlogon.exe to install the application (if the file is located on your flasdrive, just leave it there, but make sure it is renamed to winlogon.exe).
  • 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 Full 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.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
  • Right-click on mbam.exe, rename it to winlogon.exe.
  • Double-click on winlogon.exe to launch the program.
  • If that did not work, then try renaming and change the .exe extension in the same way as noted above.
  • Double-click on winlogon.scr (or whatever extension you renamed it) to launch the program.
If using Windows Vista, refer to How to Change a File Extension in Windows Vista.

regards, Elise
