Why do I keep getting this message?

Three times today I have received this message from Norton?

 

Error: "3048,3" appears on my Norton product

 

It suggests that I download Eraser. I do, Norton runs a test a detects nothing. A few minutes later I get the same message. I run another test, Norton says everything is fine. Now it's come up a third time. What is going on, and how do I resolve this problem?
