Unmovable Norton file prevents shrinking C drive partition (Windows 7)

I want to shrink my C partition but the following Norton file is preventing me from doing so because Windows Disk Manager identifies it as unmovable.

\ProgramData\Norton\{0C55C096-0F1D-4F28-AAA2-85EF591126E7}\N360_22.5.2.15\NCW\ncwperfm.db::$DATA

What does this file relate to? Do I need it? Can I move it manually? If so, where should I move it to?

Thanks in advance
