Prevention from autorun virus pen drive

Hi!
I am a desktop computer user. I am suffering from the most common and irritating virus autorun. My computer is affected by this virus, through the pen drive. When I plug in any pen drive then it automatically starts and then the autorun virus affects my computer from the pen drive.
Is there any way to get a remedy from this virus?
My Antivirus does it, but I don’t think it can remove this virus properly.
Please help me!
