PC Angel is a good program if you dont:
A) Backup your drive
Want to dual boot linux
C) Alter any registry files it protects
It has caused me more problems then saved me headaches (as I am a firm believer in backing up data and a dual boot linux user)
Its a leigit program that comes on most eMachines and Gateway comps. Dell perfers GoBack from what I know.
It usually stays out of sight until there is a problem (or thinks there is)
If anyone wants to try dual booting linux w/ PC Angel let me know I have a few tricks on how to do it w/o having to deal w/ PC Angel
