Frequently asked questions
- Is Bitdefender free antivirus really free?
- Yes. Bitdefender Antivirus Free Edition for Windows is a permanent free product, not a trial. It is limited in features, not in time.
- What is the difference between Bitdefender Free and Antivirus Plus?
- Both share the detection engine. Antivirus Plus adds multi-layer ransomware protection, anti-tracker tools, a capped VPN, safe online banking and support options the free edition does not include.
- Where is the official Bitdefender download?
- bitdefender.com. The free edition and the paid trials each have their own official download page; avoid third-party mirrors.
- Does Bitdefender slow down a PC?
- Its cloud-assisted scanning keeps day-to-day impact low. Expect noticeable disk activity only during the first full scan.
