Norton Security and disc space.

Norton Security takes a lot of disk space on my PC, just about 36 GB. So I want to know why, if Norton folder in ProgramFiles takes just about 500 Mb. Also I want to know about C:\ProgramData\Norton\{0C55C096-0F1D-4F28-AAA2-85EF591126E7} folder. What it is needed for if it contains only old information (about 22.7) and why Norton don't remove it automatically after 22.8 was downloaded?
