A frequently noted issue is the significant price increase after the initial promotional year, which can affect overall value.
System performance impact
On certain systems, especially during full scans or intensive operations, Norton may have a noticeable impact on performance.
Upgrade prompts and notifications
Some users find the frequent upgrade suggestions and promotional notifications intrusive.

Overall assessment
Norton Antivirus represents a robust and feature-rich security solution, well suited for users who want broad protection and integrated tools within a single ecosystem. Its main advantages lie in comprehensive coverage, strong threat detection, and added services beyond antivirus protection.
However, renewal pricing and a feature-heavy approach may reduce its appeal for users who prefer lightweight or low-cost solutions.
Well suited for:
Families and multi-device households
Users seeking an all-in-one security suite
Those who value additional privacy and identity tools
Less suited for:
Users with minimal security needs
Resource-constrained systems
Those looking for free or very lightweight protection
