I've noticed a notable slowdown accessing websites using any browser (I've tested IE7 and Firefox) that has Active Mode scanning enabled for it. Much slower than with V3. Speed is fine when Active Mode is unticked. EDIT - Okay things have now changed. I could repeat the slowdown in Active Mode every time earlier, but now it seems to be performing normally. Not sure why. Perhaps some interraction with my web connection? I'll keep an eye on what happens.
