How to download and install Bitdefender Antivirus Free on Windows
- Use the official source. The download button on this page opens www.bitdefender.com, the publisher's own site — that is the safe route. If you would rather we double-check the current link first, ask and we email it. Either way, never take a bitdefender antivirus free download from a mirror or a "download manager" portal, which is where bundled adware comes from.
- Pick the build for your system. Bitdefender Antivirus Free runs on Windows. On Windows take the 64-bit package unless you are on an old 32-bit installation.
- Run the installer and accept the defaults. Bitdefender ships no bundled extra software with it, so there is nothing to untick.
- Open it once before you need it. Confirming it launches and sees your files or hardware takes a minute now and saves a problem later.
- Keep it updated. Update from inside the program or from www.bitdefender.com — update prompts arriving by email or pop-up are not from the publisher.
