Stop viruses coming from pen drives

Now a days pen drives ( or USB drives ) are became necessary. But there is a problem with these pen drives. They can be very easily infected by viruses. But, we can not live without using pen drives.You can be a bit more careful when using pen drives to prevent them infecting your system with different types of viruses.
First disable auto play in your system. This prevents viruses in the pen drive from running automatically when pen drives are inserted into the system. (Please note that this will disable auto playing of CDs also).
After inserting pen drive into the system open it in explorer mode only, don't open it in My Computer.
To open Explorer, press Win+E on your keyboard.
Or right click on My Computer, and select explorer.
If My Computer is already opened, click on 'Folders' in the tool bar (or View menu> Explorer Bar> Folders).
Always open pen drive by clicking on the pen drive name from the left pane only. Don't open from right pane.
Don't open the files you don't need. If you find any file suspicious, right click on file name and select properties. It will show complete details about that file. Don't rely on icons. Some viruses use folder icon to make us think that they are folders, and most probably we will double click on that to see what is there in that folder which actually executes the virus.A little careful handling of pen drives will prevent a lot many viruses.
