Norton Virus is blocking my ability to update my conmputer

Hello,

 

I am unable to update my microsoft prgrams on my computer.  I have the Vista Home Premium operating system.  I have talked with MS and they are telling me I must disable my Norton Antivirs to update my computer.  I also have Norton Utilities running.    I am not sure why this is happing now I have had this computer for over a year and now it decides not to allow MS to update. Is there a fix for this problem?  Thank You Mark
