The remote server seems to be a Kazaa Peer-to-Peer client, 
which may not be suitable for a business environment. 

In addition, there is rumoured to be a remote exploit against Kazaa clients up to 2.0.2.  While this has not been confirmed, the reporting sources are credible.

Solution : Uninstall this software
Risk factor : Low";
