When you're choosing an antivirus plan for the next year, the first decision is about device count and operating systems, not just virus definitions. Do you need to protect a set of Windows PCs, or does your household include a mix of computers, phones, and tablets? One option is a Windows-only license; the other is a cross-platform suite that can follow your family across device types.
Quick verdict: If every computer you need to protect runs Windows, the Norton license is the simpler route. If your protection has to include Macs, iPhones, iPads, or Android phones, the Complete Antivirus suite is the broader choice.
| Product | Listed price | Coverage | Platforms | Best for |
|---|---|---|---|---|
| Norton Antivirus Internet Security CD Retail License 3 PCs 1-Year Windows | USD 29.99 | 3 PCs | Windows 8, 7, Vista, XP | Windows-only households |
| Complete Antivirus & Internet Security Suite - 5 Devices, 1 Year, PC/Mac, Activa | USD 39.99 | 5 devices | Windows, Mac, iOS, Android | Mixed-device households |
Where the Norton license wins: The Norton license fits a Windows-only household that wants a straightforward single-platform license. It explicitly names Windows 8, 7, Vista, and XP, and the system requirements are modest, which can matter if some machines are older.
Where the suite wins: The Complete Antivirus suite is the right call when your protection has to stretch across operating systems. It covers Windows 7 SP1 through 11, macOS 10.10 and later, iOS 11.2 and later, and Android 5.0 and later, and it adds a dedicated browser for safe online banking.
Norton Antivirus Internet Security CD Retail License 3 PCs 1-Year Windows
If your household runs exactly three Windows PCs, the Norton Antivirus Internet Security CD Retail License is a straightforward one-year fix. The CD format and retail license are explicit, and the listed system requirements ask for just 1 GHz, 512 MB RAM, and 200 MB of hard drive space, so it can fit older machines. The license focuses its coverage on a single platform, so there's no unused cross-platform overhead. The catch is the cap: it covers three PCs, and the compatibility list is exclusively Windows. If your family also uses Macs, iOS devices, or Android phones, those are outside this license's stated scope.
Complete Antivirus & Internet Security Suite - 5 Devices, 1 Year, PC/Mac, Activa
When your devices span Windows, Mac, iOS, and Android, the Complete Antivirus & Internet Security Suite puts five devices under one one-year license. It adds a dedicated browser for safe online banking and lists compatibility from Windows 7 SP1 through 11, macOS 10.10 or later, iOS 11.2 or later, and Android 5.0 or later. The compatibility list is broad enough to cover older and current versions of each system. The trade-off is the device cap: you get five covered devices, so a household with six or more connected devices would need something beyond this single suite.
Final choice: Pick the Norton license (USD 29.99) when your entire security setup is Windows. Pick the Complete Antivirus suite (USD 39.99) when your household uses a mix of PC, Mac, iOS, and Android devices and you want one license to cover them.
