Thanks very much, Brocker.

Yesterday, when I started the PC all the Microsoft stuff ran OK, but generated an error message whenever I shut them down.

I have managed to run a full MacAfee virus scan and Ad-Aware, with no obvious problems.

This morning, none of the Microsoft stuff will run! It seems it will only work (sort of) every other day, quite bizarre.

All my stuff is backed up remotely by Carbonite, so I won't lose anything valuable.

I'll now try to download a more recent version of Ad-Aware, and try that.

I'll also investigate 'Delivery Manager', as this keeps reporting that it has crashed when I start the PC.
