  • They diverge on capability: Avast One covers Antivirus, LibreOffice covers Full suite.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Avast One

  • Ransomware and Wi-Fi vulnerability protection only on paid plans
  • Free plan VPN is limited, no data breakthrough monitoring
  • Rebuilt app in May 2026 may have stability issues

LibreOffice

  • Real-time collaborative editing is far behind Microsoft 365 and Google Workspace, and for teams who co-edit this alone usually decides the question
  • Mobile support is weak, which is disqualifying for a workforce that reviews documents on phones
  • Complex Microsoft Office documents still lose formatting in transit, so exchange-heavy workflows need testing with real files
  • Central policy management, conditional access and audit tooling are thin against the commercial suites
  • Advanced spreadsheet work is where the gap with Excel is widest, and it affects exactly the users least willing to change

Answered from the vendors’ own pages

Avast One: Is Avast One free?

Yes. Avast One offers a free tier with antivirus, VPN (limited), and privacy tools. Paid plans start at $2.99/month for Silver and $4.19/month for Premium covering up to 5 devices.

Source
LibreOffice: Is LibreOffice really free for business use?

Yes. It is open source with no per-seat licence and no restriction on commercial use. The Document Foundation is funded by donations and sponsors.

Avast One: What does Avast One include?

Avast One provides antivirus, VPN, password manager, device cleanup, Wi-Fi security, data breach monitoring, and protection against AI-generated scams and deepfakes.

Source
LibreOffice: Does it have AI features?

No. The 26.8 release states it contains no generative AI, that documents are not transmitted to remote services, and that no component requires network access.

Avast One: Does Avast One have ransomware protection?

Ransomware protection is available only on paid plans, not the free tier. Free users get antivirus and basic protection only.

Source
LibreOffice: Can it open Microsoft Office files?

Yes, and save back to them. Round-tripping complex documents is imperfect between any two suites, so test with your own files before committing to an exchange-heavy workflow.

LibreOffice: Why do governments use it?

Two reasons: no per-seat cost at scale, and OpenDocument is an ISO standard implemented by more than one vendor, which matters for archives that must stay readable after a vendor relationship ends.

LibreOffice: What is the biggest reason not to use it?

Collaborative editing. If several people work on the same document simultaneously, Microsoft 365 and Google Workspace are substantially better and that gap is not closing.
