Desktop Shortcut Icon

Well basically I have just realised on my laptop desktop the small shortcut icon displayed in the bottom left of an Icon has changed to a sort of user icon, I was wondering how I get this back to the small arrow??? Please see picture below

Guys I now have realised it has just changed again :S:S:S:S:S

So whenever I copy something or save something new to my desktop it changes this icon :S

lol, that icon means that it is being shared on your homegroup. Why don't you make it so that your "desktop" folder is not being shared on your network?
