Not sure if Norton needs to remove a virus

Hello,

 

My name is Debbie and I have a question about a new laptop.  I just got an HP Pavilion Entertainment PC with Windows 7 for Christmas.  From the first day I started to use it, Norton has been asking me if jucheck.exe can make changes to my computer and I have clicked, "No."  Tonight I decided to look this up on the internet and some places are saying this is a virus.  My Norton scans have not picked this up.  If I click on the icon on the bottom bar of my laptop it says this is a java Update that wants to be installed.  I'm not sure if this is a virus or not, but it seems to keep trying to make changes to my laptop that Norton blocks.  Can anyone tell me what to do or if this is a virus why it is not picked up when Norton scans my laptop? 

Thank you for any help,

Debbie
