What are these VirusDefs temp files for and how do I get rid of them?

 

In the following folder I have 100 tmp###.tmp folders taking up 150.4 GB of my C Drive

 

C:\Program Files\Common Files\Symantec Shared\VirusDefs

 

What are these files and why are they there?

 

I ran Norton Cleanup, Custom Cleanup, it did not show the temp files

 

How do I remove them?
