Threat detected on remote IP address

Norton Antivirus 2010 detects a downloader file \\87.110.220.31\public\0923.jar which it cannot delete as I don't have rights. I do not know anything about this site. Obviously there is some sort of reference to this site on my PC, my questions is how do I get Norton to tell me what/where this is as deleting the remote file is not an option.

 

Regards
