Hello. I was advised after various malware infected my machine to do a clean reformat. (Please see http://www.bleepingcomputer.com/forums/t/205881/help-with-win32delfuc-and-virtumonde/ and http://www.bleepingcomputer.com/forums/t/210020/help-with-vundo-virtumonde-and-other-malware-removal/ for the history of this problem). My machine seemed fine after the clean reinstall, but not very long after I plugged in my USB flash drive with my backed up files, an error message regarding "w.exe" appeared. After running some quick scans and full scans with MBAM, multiple infections were found and seemed persistent. I performed another clean reformat, but am afraid to access any of my backed up documents. Is there a way to clean the my USB flash drives and external hds without losing information or reinfecting my machine again?

These are the log files from MBAM (sorry that I post a few, but just want to be as thorough in my explanation as possible):

Hi please reboot the PC normally to compete that removal.
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.

Next rerun mbam like this on all drives.

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select FULL scan and scan.
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Thanks for your help. There doesn't seem to be any more problems, and MBAM is returning scans with 0 entries.

Ok great! Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
