Symantec's Norton 360 security software suite delivers an all-in-one security package for daily computer use. It protects against viruses, worms and hackers, and a single subscription allows up to three of your personal computers to activate and run 360 at the same time. You may install 360 using the CD, but if your computer lacks a CD-ROM drive, you may install the program using the Norton 360 installation package.
