Thread: How to prevent a Virus on your PEN drive from infecting your PC!

1) Connect your Pen Drive or USB drive to your computer .



2) Now a dialogue window will popup asking you to choose among the options as shown in the figure.

Don't choose any of them , Just simply click Cancel.

3) Now go to Start--> Run and type cmd to open the Command Prompt window ...

4) Now go to My Computer and Check the Drive letter of your USB drive or Pen Drive. ( E.g. If it is written Kingston (I:) , then I: will be the drive letter ...)

5) In the Command Window ( cmd ) , type the drive letter: and Hit Enter ...

6) Now type dir/w/o/a/p and Hit Enter

7) You will get a list of files . In the list , search if anyone of the following do exist
* 1. Autorun.inf
* 2. New Folder.exe
* 3. Bha.vbs
* 4. Iexplore.vbs
* 5. Info.exe
* 6. New_Folder.exe
* 7. Ravmon.exe
* 8. RVHost.exe or any other files with .exe Extension .

8) If you find any one of the files above , Run the command attrib -h -r -s -a *.* and Hit Enter.

9) Now Delete each File using the following Command del filename ( E.g del autorun.inf)

10)That's it . Now just scan your USB drive with the anti virus you have to ensure that you made your Pen Drive free of Virus .

Are you sure this will work if Autorun.inf is present?
In my experience, the only sure-fire solution is to disable autorun completely using a tool like TweakUI and then going for removing the files in the way you posted.

Not sure! I haven't tried it yet. I use NOD32 and so far it has always detected viruses as soon as i plug in the usb drive

I use some little free click and forget tools named USB Vaccine from Panda Antivirus that could be used to disable autorun completely from your PC or your thumb drive.

Here, have a look. Its work for me, hope it will work for you too
