Choosing one-year antivirus security and privacy protection mainly comes down to how many devices you need to cover, which operating systems you use, and whether you prefer a product key or a physical disc. Four one-year options are listed from $19.99 to $39.99: a single-PC Norton product key, a three-device Norton 360 Deluxe card, a five-device cross-platform suite, and a three-PC CD for older Microsoft Windows systems.
If you have one Windows PC, the Norton Internet Security 2026/360 Deluxe covers a single machine with a PC Card. If you need three devices across Windows, macOS, Android, or iOS, Norton 360 Deluxe fits. For five devices with PC, Mac, iOS, and Android reach, the Complete Antivirus & Internet Security Suite has the largest device count. If you want a physical CD for an older Windows machine, the Norton Antivirus Internet Security CD covers three PCs.

Product notes
#### Norton 360 Deluxe - 3 Devices, 1 Year
This is a product key card for Norton 360 Deluxe, valid for three devices and one year. The Windows, macOS, Android, and iOS support makes it a fit for a mixed household. At $26.95, it sits between the $19.99 single-PC option and the $39.99 five-device suite. It also carries the 2026 edition label in its title. The tradeoff is the device count: three devices is a middle ground, so if you need five, the suite option covers more. If you want a physical disc, this is a key card rather than a CD.
#### Complete Antivirus & Internet Security Suite - 5 Devices, 1 Year
This suite covers five devices for one year at $39.99, the highest listed price in this group and the largest device count. It supports Windows, macOS, iOS, and Android, and includes safe online banking browser features. If your household has more than three devices, this is the only one of the four with a five-device allowance. The main tradeoff is the price: you pay the top of the range for that extra device coverage. For a single PC or a three-device household, the lower-priced Norton key cards may be enough.
#### Norton Internet Security 2026/360 Deluxe - 1 PC, 1 Year
This is the lowest listed price in the group at $19.99. The PC Card format and Microsoft Windows support from Windows 10 back to Windows XP make it a straightforward single-PC choice. The title includes 2026/360 Deluxe, and it includes a global license with installation support. The limitation is device count: one PC. If you have multiple PCs or mobile devices, you will need the three-device or five-device plans. For a single Windows machine, the $19.99 price point is the most direct fit in this comparison.
#### Norton Antivirus Internet Security CD - 3 PCs, 1 Year
The CD retail license covers three PCs for one year and is priced at $29.99. This is the only physical-disc option in the group, with compatibility for Microsoft Windows 8, 7, Vista, and XP. Minimum requirements include a 1 GHz processor, 512 MB RAM, and 200 MB hard drive space, which suits modest hardware. The tradeoff is the older operating system list: the Norton Internet Security 2026/360 Deluxe lists Windows 10 support, while this CD lists Windows 8 and earlier. For an older Windows PC or a preference for a disc, this is the pick.
Final recommendation by use case
- Single Windows PC: Norton Internet Security 2026/360 Deluxe.
- Three-device mixed household: Norton 360 Deluxe.
- Five-device cross-platform coverage: Complete Antivirus & Internet Security Suite.
- Older Windows PC with a disc: Norton Antivirus Internet Security CD.
