All of Norton's anti-malware offerings include Norton AntiVirus, the heart of Internet security. In 2009, Symantec completely rebuilt the Norton AntiVirus program lineup. They now install (and uninstall) much faster, boot faster, and run faster than ever before, as well as faster than the competition.
The retail version of Comcast's Norton is called Norton 360. It has an excellent Backup utility. Have you backed up your data, your photos, your music, your financials recently?
Go to http://security.comcast.net/norton/resi/ - or contact me. I can install it remotely for you and help with a handful of critical settings. Of course, I'm always happy to schedule onsite appointments for you.
If you're a Verizon customer, you can buy Norton. Note that Verizon will provide MacAfee for you, but there is a monthly charge for it. Not a very good deal, in my book.
