If you're seeing the entry when VoiceAttack starts, it'll likely stem from the command that runs when the profile loads.
You should see a "Profile startup : ''" message with a purple icon naming the command(which you can double-click to open the command), if that is the case.
You can also find out which command runs on profile load by clicking
to open the "Edit a Profile" window,
to open the "Profile Options", and in the "Profile General" tab check which command is listed under "Execute a command each time this profile is loaded".
