Comcast Norton Security Suite Vs my Norton Antivirus program

I recently signed up for Comcast cable for my tv and internet. I read that they have included in their package the Norton Security Suite. I currently have Norton antivirus. I found a table on Norton website which showed what items where covered between the two programs and it looked to me that the Security Suite exceeded my antivirus program. Is this correct? Do I need to buy the antivirus program if I keep Comcast?

thanks,
