Hi rstout01,
The Symantec PGP login that you are getting is because the machine is encrypted with software.
This is a Data/Disk encryption product from Symantec, please see the below link for more details on it.

The only way to get into it is providing the password for the bootguard (encrypted machine), else you can format the disk and install new OS and continue using the machine.
