I think Sophos is pants myself. We have a the same arrangement as Lancs, that all the schools get Sophos for free, and it's not worth that! The remote admin thingy has never worked, and I know it's not just me, because techies from other schools have offered advice & looked at it & can't get it to work. I've had to install it manually on every machine.
And it's always stopping because of a virus that keeps attacking the machines that Sophos can't stop.
The only plus point is that the lightening bolt greys out, so you know that the machine is infected.
Having said that, in Sophos defence, the kids do keep de-activating it, because the ICT teacher told them it was like a VNC type of program (pillock), and they won't believe me when I tell then it's not!
