Protect your PC from USB drives virus.

Friends many of your PC/laptop’s normally gets virus because of Pen Drives or USB devices (Even PC’s who are not connected to network ). Some Virus like Ravmon Virus , Heap41a worm which are not detected by anti virus normally spreads mostly by the Pen Drives . In such a case what can you do to prevent your PC from getting infected with Virus that spreads through USB devices or Pen Drives ?


You can protect your PC by just following the simple steps below . It won’t take much time.

  • Connect your Pen Drive or USB drive to your computer .
  • 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. 
  • Now go to Start–> Run and type cmd to open the Command Prompt window .                                
  • 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 .)                                                
  • In the Command Window ( cmd ) , type the drive letter: and Hit Enter .                                                                                                                      
  • Now type dir/w/o/a/p and Hit Enter
  • You will get a list of files . In the list, search if anyone of the following do exist
    • Autorun.inf                                                                                                                 
    • New Folder.exe                                                                                                             
    • Bha.vbs                                                                                                                      
    • Iexplore.vbs                                                                                                                              
    • Info.exe                                                                                                                                           
    • New_Folder.exe                                                                                                                       
    • Ravmon.exe                                                                                                                                 
    • RVHost.exe
    • Knight.exe
    • ….. or any other files with .exe extension, not created by you.
  • If you find any one of the files above , Run the command attrib -h -r -s -a *.* and Hit Enter.
  • Now Delete each File using the following Command del filename ( E.g del autorun.inf ) .
  • 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 .

These are my findings, I don’t take any responsibility of restoring any file or mistakenly deleted files.
