Updating to Norton Internet Security 2010 On Old PC

I have an old MESH Matrix XP 1800 TI computer purchased in 2002, which has a ASUS A7A266-E motherboard, a NVIDIA GeForce3 Ti 200 graphics card, 1.5 GB of PC2100 DDR memory, running Microsoft Windows XP Home Edition Service Pack 3.

 

At present I am running Norton Internet Security 2009 version 16.8.0.41 without any problems.

 

Will there be any problems if I update to Norton Internet Security 2010 or should I stay with Norton Internet Security 2009.

 

What are the advantages of Norton Internet Security 2010 over Norton Internet Security 2009.
