Hi Pete!
I use
Avast which has some nice features (anti theft as well as anti malwear).
It could be worth investing in
Tasker... I am pretty sure that you can create all of the features you are after and more. I am not any good with it, having only played about a little bit, but am sure that you would find
Tasker - Android Forums a useful place... the members in there would be able to help you get anything you wanted sorted... there is already a task that takes a picture and emails it to a specified email address when there have been too many incorrect pattern lock entries (
