Norton 2012 NetDetectJob error

Hello,

 

For the last couple of days I notice this arror has appeared in the SchedLgU.txt log in my Windows Directory.

 

 

"Symantec NetDetect.job" (NDetect.exe) 28/07/2012 02:15:00 ** ERROR **
    Unable to start task.
    The specific error is:
    0x80070002: The system cannot find the file specified.
    Try using the Task page Browse button to locate the application.

 

My Internet Security seems to be operating OK so what does this error mean.

 

I appreciate any help or advice.

 

Regards,

 

Connie
