Can anyone say, why is there an bunch of Groove files, including a Groove.exe installed when SkyDrive Pro is installed? Is that a legitimate file or virus?? I recently reinstalled my SkyDrive Pro using the link provided at the Office 365 SharePoint link. I noticed thereafter that PowerPoint wouldn't open files from my Sync folder or from my SkyDrive Pro site.

In searching the hidden folders, I noticed these "Groove" files along with a Groove.exe shown in the notification area of my Windows Taskbar.

Of course I deleted all the Groove files I could find and uninstalled the SkyDrive Pro. This seems very suspicious to me. Why would SkyDrive use files or exe named "Groove"

Any guidance greatly appreciated!!
