autorun.inf In Pen Drive

This virus is activated when we double click open the Pen Drive.
The autorun file in that drive runs a .exe file to activate the virus.
So, you must remove these two files (autorun.inf and a .exe file) from the pen drive.
Otherwise, the virus will roll back whole things what we have done to remove them.
These files may be hidden system files, to show the files, follow these steps:

1. Select Run from Start menu.
2. Type cmd and hit Enter.
3. Type the pen drive letter with a colon (for eg: J: ) and hit Enter.
4. Now type as following:
attrib -h -a -r -s and hit Enter.
5. Now, from My Computer, right click (do not double click) on the pen drive and select Open.
6. Delete the files autorun.inf and a .exe file from there.
Restart the system.
