| Free plan | Paid plans Norton advertises 7-day free trials that require a payment method and convert to a paid subscription unless canceled; the reviewed official pages do not identify a permanent free antivirus plan. | Free plan available Bitdefender Antivirus Free is described as completely free forever with no time limit and no trial required, but it is Windows-only. The official downloads page separately describes 30-day and 14-day trials for paid products and Android Mobile Security. |

How to read the differences
Start with your requirements.
The notes below describe differences in the sourced records, not performance or features proven absent. Different vendors use different names and describe their plans at different levels of detail.
Look at ongoing free access
Norton has no verified ongoing free plan; Bitdefender has a verified free plan.
Read the separate free-plan notes in the table. Trials, refunds, quotas and ongoing free tiers are different things.

Read the full billing terms
Neither record has a verified numeric monthly USD starting price. Compare the official plans rather than treating either price as zero.
A lower displayed price is not a direct value ranking. Billing commitments, introductory periods, renewals, country, taxes and included features differ by plan.
Your needs make the choice.
Use the comparison to shortlist, not to pick a universal winner. Review each product's strengths and things to consider, confirm support for your devices and read the current plan terms. The checked dates in the table show when the source information was reviewed; this is not a hands-on test.
