It's engine 4.1.40. The AV is only scanning his local drives, inbound only. I don't know why it's taking so long, maybe it's because of some temp files being created. Anyway, I'll change the engine to 4.1.60.

It takes about 1 second when Netshield is not activated. Can anyone point me in some direction. TAI.
