Explorer.exe detected as P2P application

Hello,

I have been getting this Event Description: [SID: 20566] Audit: P2P BitTorrent Traffic attack blocked. Traffic has been blocked for this application: C:\WINDOWS\EXPLORER.EXE

I have check there is not torrent related application or add-in is install in the windows 7 computer.

Could you please suggest me some solution why it keeps triggering in the Outbound logs with this Event.

Thanks!

Ayush
