How to unlock scheduled scans?

Hello everyone:

 

Symantec Antivirus Scan version 10.0.0359, scan engine 103.0.2.7.

PC is is gift from someone that was at college.

Two scheduled scans are set an locked.

I think this means network administrator must unlock them.

I have PC admin rights...but this PC will never be connected to college network again.

How can I remove these scans?

Or do I need to remove the entire antivirus program through control add/remove programs?

Thanks for any help.

Bob
