sonar removes my MSWorks.exe

Just installed Norton internet security 2011, and got message that Sonar  has deleted my MSworks.exe due to threat.

 

So I turned off Sonar protection permanently, reinstalled Microsoft Works yesterday, but MSworks.exe was deleted again today, I know Microsoft Works 4.5a is 2000 program that I've been using since 2000 had no problem with 360 program that I have been using it seems like forever, but install different Norton product and now this problem
