File purpose and description:
Usnsvc.exe is a program file which may have been installed on your computer by yourself. The exact disk location is also shown below to verfiy it is not spyware, as many spyware programs use similiar names and just locate them elsewhere on your hard drive. The main purpose of this is to work with MSN messenger, and if you have recently installed MSN messenger or upgraded it, the usnsvc.exe program may not appear in your tasklist. This will not be in your startup list but will be in your tasklist as a running process. This goes by the name MSN messenger sharing USN journal reader service. This is not considered to be spyware or adware related. Windows Live Messenger will not run without this file. (See the details below for the actual location of this file.)
Actual file or task name: (Note that you can view the entire list here)
This is an executable program.
File or folder location:
This will be located at C:\Program Files\MSN Messenger\usnsvc.exe
Be aware that many tasks will be similiar names to existing tasks or processes.
You can always view the running tasks on your computer by pressing ctrl-alt-del to view the windows
"task manager", and then view the "processes" tab. This will show you all tasks running or currently active
on your PC. Although this shows you all running tasks, it does not show dll file thats are loaded, as they
get loaded as part of other processes. Many spyware writers attempt to hide their files
on your computer, for example, usnsvc.exe may be intentionally misspelled to look like a similiar task, or spyware may be named very
similiar to a Windows system task. The reason they do this is so you cannot easily recognize the name in your tasklist
as I have mentioned above. Make sure always check the location of the file if you are concerned.
You can always find the location of usnsvc.exe on your computer by using your Windows search options, but
I will also try to list the file location of every file described on this website, so you can verify the correct location. You can view the entire tasklist directory with the link below.
