8 Gigs of "SDSDefs"?

Hi, I see a tree like the following: 

C:\Program Files (x86)\Norton Security\NortonData\22.7.0.76\Definitions\SDSDefs with 111 folders, each of which is about 90 to 100 megs.   Altogether these are taking up 8.3 gigs of space.   I suspect that is not correct.

Windows 10, Norton Security 22.9.12.  

Can someone help me clean these out?  Do I have to (sigh) uninstall and reinstall?  Any other suggestion would be greatly appreciated.

Thanks, Michael
