Download Bitdefender Antivirus Free for Windows from Bitdefender’s official page, or start the Bitdefender Antivirus Plus 30-day trial there. Install either product through Bitdefender Central. The former Antivirus Free Edition is retired, so avoid legacy installers and third-party download sites.
Which Bitdefender Windows version should you download?
Bitdefender Antivirus Free for Windows
The current free product is called Bitdefender Antivirus Free for Windows. Bitdefender says it launched in March 2022 to replace the older Free Edition. Its support page describes real-time malware protection and customizable scan scheduling, without a trial period or hidden cost. Get it from Bitdefender’s official Free page.
Bitdefender Antivirus Plus
Antivirus Plus is a subscription product with a 30-day trial. Bitdefender’s US product page presents 1-device and 3-device options and lists features including malware and ransomware protection, scam protection, a limited VPN allowance, and data breach detection. Features and offers can vary by region and change over time, so check the product page for the current terms where you live.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The trial is a time-limited way to try Plus, not a permanent free edition. Bitdefender’s trial guidance says it expires after 30 days; after that, the product cannot be used without a subscription.

The old Antivirus Free Edition
The previous Antivirus Free Edition for Windows is no longer supported. Bitdefender’s end-of-life table gives December 8, 2021, as its end-of-sales date, December 31, 2021, as end of life, and June 30, 2022, as end of support. The listed migration product is Bitdefender Antivirus Free for Windows.
Free versus Plus: what changes?
Choose based on the plan and features you need rather than assuming one tier is universally better. Antivirus Free provides core real-time malware protection and scheduled scans. Plus adds a time-limited trial and subscription options, with the features shown on Bitdefender’s regional product page.

Understand the Plus trial and renewal terms
