That .vbs file is malware and related to a flash drive infection.
A flash drive
(usb, pen, thumb, jump) infection
usually involve malware that modifies/loads an autorun.inf
(text-based configuration) file into the root folder of all drives
(internal, external, removable) along with a malicious executable. When removable media such as a CD/DVD is inserted (mounted), autorun
looks for autorun.inf and automatically executes the malicious file to run silently on your computer. For flash drives and other USB storage, autorun.ini uses the Windows Explorer's right-click context menu so that the standard "Open" or "Explore" command starts the file. Malware modifies the context menu (adds a new default command) and redirects to executing the malicious file if the "Open" command is used or double-clicking on the drive icon. When a flash drive becomes infected, the Trojan will infect a system when the removable media is inserted if autorun has not been disabled. Keep in mind that autorun.inf can also be a legitimate file which other legitimate programs depend on so the presence of that file may not always be an indication of infection. To learn more about this risk, please read:
Please download Flash_Disinfector
by sUBs and save it to your desktop.
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. Do not delete this folder as it helps to prevent the installation of a malicious autorun.ini file on the root drive and executing other malicious files which can infect the computer. Please read About Flash Disinfector by Papakid and USB/Flash Drive Safety by TheJoker.Note
- 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.
: As an alternative to Flash Disinfector, you can download and use Panda USB Vaccine
.alternate download link 1alternate download link 2
Note: Computer Vaccination will prevent any AutoRun file from running, regardless of whether the removable device is infected or not. USB Vaccination disables the autorun file so it cannot be read, modified or replaced and creates an AUTORUN_.INF as protection against malicious code. The Panda Resarch Blog advises that once USB drives have been vaccinated, they cannot be reversed except with a format. If you do this, be sure to back up your data files first or they will be lost during the formatting process.
- Double-click on USBVaccineSetup.exe to install the program to C:\Program Files\Panda USB Vaccine.
- Read and accept the license agreement, then click Next.
- When setup completes, make sure "Launch Panda USB Vaccine" is checked and click Finish to open the program.
- Click the Vaccinate computer button. It should now show a green checkmark and confirm Computer vaccinated.
- Hold down the Shift key and insert your USB flash drive.
- When the name of the drive appears in the dialog box, click the button to Vaccinate USB drive(s).
- Exit the program when done
Please download Autoruns
, search for the related entry and then delete it.
- Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if you're not sure how to do this. Vista users refer to these instructions.)
- Open the folder and double-click on autoruns.exe to launch it.
- Please be patient as it scans and populates the entries.
- When done scanning, it will say Ready at the bottom.
- Scroll through the list and look for a startup entry related to the file (jargon.vbs) in the error message.
- If found, right-click on the entry and choose delete.
- Reboot your computer and see if the startup error returns.
If you're going to keep and use Autoruns, be sure to read:
