Thank you Greg. I was hoping someone else would jump in to let Alias know
that you don't have to turn off your A/V to run a defrag. My biggest
concern was the fact that he/she was saying it was 'not bright' to run a
defrag with your A/V turned on.

IMO turning your A/V off to run a defrag leaves your system vulnerable
during that time and isn't worth the risk with the number of viruses out
there today.
