Sonar facepalm

i was playing a video game when suddenly i had a bsod (blue screen of death), so i restarted the computer and when i logged into windows i discovered to my amasement that Norton Sonar had removed and deleted a file that belongs to my nvidia graphics drivers.

 

the file is called nvcpl.dll,

i'm guessing this is a false positive and safe to restore? my pc seems screwed up since norton removed this file.
