With Sophos 8 (currently 8.0.2c) on OS X Lion, the on-access scanner only starts between 30 seconds and 1 minute after login on first boot. The Sophos shield is usually visible for much of that period, but grey. I can confirm the delay by running the console after login, and waiting for the Sophos log to record the on-access scanner starting.
Is this delay normal? It seems odd there should be this noticeable period when the computer is usable, but unprotected.
