Please help!? Norton IS 360 wont run scans

Hi I have Norton 360 running on my computer and the program wont run a full system scan (nor any other scan). This has been the case for the past 8 days. The program does update properly, and the 'get support' update is also running properly. The program does run a full system scan if I run the program in safe mode. But the scans wont run when I start windows properly. 

Can someone please getting the program to run anti-virus scans?

Sincerely,
