Can I Schedule a program that requires user input?

[Pete]

I run Lavasoft's Ad-Aware program to remove the constant build-up of
spyware on my PC.

I would like to be able to run this program automatically overnight
using scheduler, however when I have tried, Scheduler reports that the
program 'Could not Start'. I assume that this is because the program
requires the Return key to be pressed twice in order to start the
program running.

Has anyone any suggestions ?

Many thanks
Pete
