it's a pretty poor state of affairs if your OS doesn't have the ability to run realtime AV software
I don't want to name names, but there are at least two AV products out there that can slow down file-intensive operations by 80 to 90 percent, irrespective of OS (i.e. the operations take 5 to 10 times as long to complete). I am no fan of Vista, but Vista may not be to blame.
