Fishing here, can't seem to find anything on this. running win7-64bit on a Dell E6410 with intel I7 chipset. I had MSE 64bit client installed copying from HD to USB was FAST, over 29MBS per second. With ForeFront, falls to about 9MBS. Haven't tried with other av clients since corp wants to use ffront. Anyone seen this? The laptop has a factor image from Dell on it, with zero "bloatware", all patches and office 2010. My next "test" is to put AntiVir on it and see what that does.
