Trouble:

We have received lot of problems where computers got infected easily by the viruses in the pen drives, pen drives have become one of the most easiest carriers of various types of viruses these days.

We will tell you how pen drives normally infect your computer systems and how can you open pen drive safely and back up your important data.

How a virus in your pen drive infects?

Most of the active viruses infect your windows system as soon as you double click on the Pen Drive icon in your my computer. As virus always creates a autorun.inf file which is a system ,hidden and a read only file on your pen drive. It point to the main virus file which is also located on the pen drive. When user double clicks on the pen drive files pointed by the autorun.inf got executed which copies the virus files on your system.

The image below shows the Autorun file entries in some special characters when you right click on the drive.

virus-pendrive

Let’s see how can you protect yourself by following certain practices.


Fix:

Let’s discuss these practices one by one:

1. Disable Autorun on Your Pen Drive:

  • Open to Start >> Run and type “gpedit.msc” (without quotes) and press enter. This will open Group policy editor.
  • Browse to Administrative templates >> System >> double click on Turn off Autoplay click on Enabled and Under Settings >> Select All Drives in the drop down and click OK (as shown in the image below)

2. Scan Your Pen Drive:

Whenever you insert your pen drive / portable drive into USB port on your system make sure to run a virus scan with your anti virus before opening your pen drive contents in windows explorer.

3. Use FreeCommander:

FreeCommander is again a file explorer like windows explorer, so you just need to download it by clicking here and install it.

After installing open your pen drive through FreeCommander (as shown in the image below)

freecommander-usbdrive-virus

Check if there are some additional files like autorun.inf , Funny UST Scandal.avi.exe ,Ravmon.exe ,New Folder.exe etc or any other file which you have not copied or created, delete all these suspicious files on your pen drive.

 

Quick Update: 26th March 2008

4. Use your virus infected pen drive: You can also use your virus infected pen drives to copy your important data in worst circumstances.

 

How to backup your important data when your pen drive is infected with a virus

 

 

 

a. Insert your pen drive into the usb port, if it detects your drive you will see it in my computer.

b. Now don’t double click on your drive, rather open the pen drive contents by typing the drive letter.

For Example: type g: and press enter if your pen drive is shown as new g drive under my computer.    

c. Copy your important files from your pen drive close the window and format your pen drive after then.

 

If you are still suspicious about the existence virus files on your pen drive, you can remove virus from your pen drive through command prompt by the method suggested by Madhur here in this article

thks soo much

but i just have one question, if anyone could help please,
after using the free commander, and trying to delete those .exe files, these files appear again and again.

just need ur help here, i cant clean those virus.

thks

Rohit June 29, 2008 at 7:25 am

@Dosh

If the files are appearing again themselves, there must be some more files which are generating them . Look for some suspicious autorun or dll files etc, that could be generating those executable files. Delete such suspicious files.

Dear sir,

I have a problem with my flash.when i connected it to the computer the following message appears.

” The disk can not be written because the it is write protected. Please remove the write protection from the volume in drive
\Drive\Device\Harddisk1\DR11 ”

When i try to format it, it apperas a message “Disk is write protected”.I can’t copy new files into it (windows and linux).
A virus like software is inside it called “DriveGuard.exe” (microsoft corporation)and its autorun file. Please tell me how to
remove these files from flash and how to remove write protection from flash.To my another flash can’t copy more than 600 MB
(its size is 2GB). When it overcomes 600 MB is also appears the write protected message. But it does not contain the “DriveGuard” and
autorun filefile.

S/N : G01GNMW680022
Model : PD1

Yours faithfully

I think my pen drive and Mp3 infected by same virus. Even after I format both of them, there is still a text document inside it. The file named “service” and when I click in that file it just all “aaaaaaaaaaaaaaaaaaaa” inside. No matter how many times I format or deleted it manually, that file still will appear with the same name and contain. I have tried few anti viruses to scan it (panda/ avira/ norton/ 360) but all the anti viruses did not categorize this file as virus. Can anybody kindly advise the solution?
