Should have done rooted install for GPS

I would like to enable the GPS tracking feature, but am told I need to install “avast! Anti-Theft rooted” which I should have done initially. Do I need to uninstall avast! and redo the install but make it rooted this time around, or is there an option I am missing?

GPS tracking works always if GPS is turned on, you just need root to automatically enable GPS if it is turned off.
If you want that feature, you need to uninstall Anti-Theft and reinstall it rooted.
