Process name: Messenger Sharing USN Journal Reader Service

Product: Windows Live Messenger

Support: Help link   Update link   Uninstall tool  

Company: Microsoft (microsoft.com)

File: usnsvc.exe


A background process for Windows Live Messenger, the USN Journal Reader Service runs when Folder Sharing is enabled in Live Messenger. This synchronizes folders on your account to other machines as well as other users. It does not adversely affect performance or functionality if you disable the sharing service, it will just remove the synchronization portions. Windows Live Messenger is a chat application that syncs with your Microsoft email, address book, song library, and many other options. First released in 1999, Windows Live Messenger now has the ability to integrate with Facebook and Yahoo Messenger.http://www.neuber.com/taskmanager/process/usnsvc.exe.html

it causes MSN messenger to freeze up and other annoying bugs. personal experience ending its process stopped msn live from freezing up mid sentance. Unabonger
Part of Windows messenger it seems, terminated with no issues to messenger
Can also appear under C:\Windows directory... This is NOT the MSUSN Journal service. This executable establishes a connection to irc.criming.net:8069 and restarts when killed. Nod32 failed to detect this, but file has been submitted for analysis James B
eigendlich garnichts whiti
Runs on a clean, sandboxed, install of Windows Live Messenger, all scans find nothing, and antiviruses find no suspicious activity. Just make sure it's on the proper directory.

my antivirus program detected this after i got hacked(with a keylogger program) so i think this must have been the keylogger program oscar
