[Help Needed] - How to Delete autorun.inf?

In one of my folders, there is this particular file which I cannot delete called "autorun.inf". I have read in some of the forums mentioning that it is a virus. Most of the solutions are meant for PC.
However, I can't find any solution to delete this from my Macbook Pro.
For your info - the sharing and permission for this file is for both "Read & Write" but yet I cannot delete it.
Please help... thanks..
