|This is "Nero Scout" - a feature that nobody uses and it gets in your hair.|
Your symptoms are a bit unusual but for starters do this:
Open "My Computer", right click on "Nero Scout", select "Options".
Uncheck the box "Enable Nero Scout" in order to disable Nero Scout.
Also uncheck the box "Show NeroDesktop Search“.
Restart the computer and see if that fixes it. Shout back if it is obstinate
because there are a couple of other things you can do to kill it off.
Always pop back and let us know the outcome - thanks
