Bitdefender Antivirus Free Edition
A permanently free Windows antivirus from a top-tier detection vendor.
Bitdefender Antivirus Free Edition is the free Windows product from Bitdefender. It is not a trial and it does not expire. It provides real-time malware protection, on-demand and scheduled scanning, and web filtering that blocks known malicious and phishing pages.
It is the answer to a large slice of US free-antivirus search intent: people who want vendor-grade detection without a subscription and without the nag-heavy behaviour some free products are known for.

Frequently asked questions
- Does Bitdefender Free expire?
- No. It is a permanent free edition, not a 30-day trial.
- Is Bitdefender Free better than Microsoft Defender?
- Both are capable. Bitdefender's engine has a longer independent-testing track record, while Defender is deeply integrated into Windows and needs no installation. Neither choice is wrong for a careful user.
- Can I use Bitdefender Free at work?
- No. The free edition is licensed for personal, non-commercial use.
