Apple IE DAV has stopped working

I use a PC (Windows) laptop for work and I have itunes installed and use it to manage and sync with my iPad. I use iCloud and iMatch.   I also use outlook and have it synced to iCloud.


Well, all of a sudden I am now getting this message when I start my laptop up:


"Apple IE DAV has stopped working"


Can someone tell me what this means and how to fix it.
