I got this error in windows,
I have uninstalled Norton as guided by a forum,
But that didn't work out,
Some Forum said the problem may be due to "Nero Scout Process" & stop the Process,
But in my processes list Nero Was there!
Finally did this,
Just go Start>>Run and type services.msc
Then stop & disable NMIndexingService.
Then stop & disable NMIndexingService.
