Safe when in the right directory. Automatically runs when computer is idle for abput 10 mins. To turn off, go to the hard drive's properties and untick the Indexing Services box.

I have a returning problem with it. When it pops up I must shut the computer down by the off switch nothing else works then.

All I know is it hits performance in a big way and I have to stop it (Task manager) to get any decent performance from the server. I schedule a defrag job and expect it to stop once I stop the job if over running.

In my case McAfee Internet Security had started this task. No window was visible. So in my case Windows Defrag was not running, but nothing wrong.

NTFS defragger, windows will start this when the PC is idle for some time.

It is a windows service. It is called when system is idle and windows optimize is run. It can be turned off with the tweakui downloadable from microsoft. Uncheck the "optimize hard disk when idle" option under the General panel. TweakUI can be downloaded here http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx

this program still ran after closing it out - (hit stop) and everything. thought it was a worm running, could be considering I'm running virus scanner now. needless to say it will not stop when I go to TM and say 'end process' / 'end process tree'
