Understanding Antivirus False Positives

A detection can be mistaken, but dismissing an alert without verification can expose a device to real harm.

Who this guide is for

Users deciding whether a quarantined file is safe to restore.

Practical checklist

1. Read the exact detection name, file path, time, and action recorded in the security log.
2. Confirm how the file arrived and whether you expected it from a trustworthy source.
3. Check its digital signature and hash when the publisher supplies a trusted comparison value.
4. Submit a suspected false positive through the antivirus vendor’s official review channel.
5. Restore the file only after verification and use the narrowest possible exception if one is required.

Common mistake to avoid

Disabling protection or adding a broad exclusion simply because a familiar-looking file was blocked.

A safer way to proceed

Keep the file isolated while you verify its origin, signature, and vendor guidance.

Product features, prices, eligibility, and policies can change. Confirm important details on the provider’s official website before purchasing, renewing, changing account settings, or acting on a security alert. If an incident may involve financial loss, sensitive personal data, or a business network, consider qualified professional help and the appropriate official reporting channel.
