If you're on Exchange 2000 server, or if you're on Exchange 2003 and have exposed the M drive, scanning or backing up the M drive is a sure way to get into trouble. The same applies if you have used Windows Explorer and change the security settings on the M drive.
This much-publicized worst practice is not recommended and can cause negative performance impacts -- including complete server outages -- of your messaging infrastructure.
Top 10 Exchange performance worst practices

#6: Throttle the RAM available to Exchange
#7: Virus scan and back up the M drive
