I think i found out how to force support for ED2K P2P clients (Overnet,eMule,edonkey2000).
Left-click on “a” ball and select Standard Shield,click customize,go to Scanner (Advanced) tab,now look for Scan created/modified files.
Add these extensions in the Additional extensions field:
PART,MET
This should scan all incoming chunk files for upper P2P programs.
If you have Scan All files you don’t need to do all this.
If you know any other P2P related temporary files extension let us know here
