Win7 Scheduled tasks

Am running Win7 and NIS 19.9.1.4. (Not sure I want to upgrade this yet.) 

 

Going through the scheduled tasks in my computer and found two entries I'm not sure about what they do and thus do I need them.  One is Norton Error Analyser which runs daily at 23.00 and the other is Norton Error Processor which runs daily at 00.00.  Can any one throw any light.
