What is auto.vbs
From what you describe, it appears to be a USB flash drive infection
. Flash (usb, pen, thumb, jump) drive infections usually involve malware that modifies and loads an autorun.inf
(configuration) file into the root folder of all drives
(internal, external, removable) along with a malicious executable. When the removable media is inserted (mounted), autorun looks for autorun.inf and automatically executes the malicious file to run silently on your computer. When a flash drive becomes infected, the Trojan will infect a system when the removable media is inserted if autorun has not been disabled. Read When is AUTORUN.INF really an AUTORUN.INF?
Please download Flash_Disinfector
by sUBs and save it to your desktop.
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.
- Double-click Flash_Disinfector.exe to run the tool and follow any prompts that may appear.
- If asked to insert your USB flash drive and other removable drives, please do so and allow the utility to clean up them 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: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with disinfection. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. 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. Click this link to see a list of programs that should be disabled.
- 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.
