Hi guys, I hope you will be able to help me with my problem.

Basically, one fateful day, I opened an email from a friend of mine, and like an idiot, opened one of the attachments which turned out to be a virus. The virus completely f***ed up my laptop, and I had to reformat it it etc etc. I also used another laptop which was infected by the same virus, and I had no idea how.
Little did I know, the virus had infected my USB Hard Drive and infected the second laptop.

Since then, my laptops are fixed, but the dreaded virus remains on the USB Harddrive. I am currently running Windows Vista, and have ESET NOD32 virus protection and Windows firewall.

I have ALOT of precious material on my USB Hardrive which I would really like to salvage by deleting the damned virus from it. I have read about turning Autorun off and scanning the USB drive in this way, but I did that and attached my USB drive to the laptop, but got scared when I saw my system recognising the attached hardware, so quickly took the USB cable out the laptop.

Also, ESET NOD 32 was totally useless last time against the virus, so what is the best virus scanner to use for the USB HDD, so that I can be certain it is clean?

Your help and advice would be warmly appreciated guys, thank you.

Hello moneymayweather:

Flash_Disinfector is a specialized fix tool created by sUBs to remove infections that load an autorun.inf file on removable media. Flash_Disinfector will create a hidden "dummy" autorun folder/file with special permissions in each partition and every external drive that was connected when the tool was run. This folder helps to keep the malicious autorun.ini file from being installed on the root drive and running other malicious files which will infect the 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.

^done all the above.

however I'm not sure the program ran correctly as it closed down of its own accord and was a very quick process when executed! seems it did its thing though.

where do I go from here boopme?

Well let"s look and see what else uis here. Sometimes the malware does funky things as it dets pulled from the registry.

Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

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

alternate download link

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 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 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 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. 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.

Ok, so now run MBAM on the other PC. You will only need a Quick scan. We'lll refer to that as Compy B.
Compy A is no longer having Issues?

hmm, but how!? which program would have done it.? because malware bytes detected nothing as far as i can see.

also, is it safe to browse the USB HDD? I noticed some rogue files in there which I believed were placed there by the virus, I would like to delete them.

and also, would executing any files on the USB HDD trigger transfer of the virus (if one is still present)?

Hello didn't we run the flash disinfector earlier? that should have cleaned the Mobile drive.

You may want to consider reformatting the USB.
