Bitdefender offers a free antivirus download for Windows and a separate free antivirus app for Android. The reviewed iPhone listing is different: it is Bitdefender Mobile Security, which offers premium protection through a limited free trial rather than the same perpetual free product. Use Bitdefender’s official local Windows page or Google Play for Android; an APK search does not establish an official direct-download route.
Choose the official download for your device
| Device | What is available | Official route |
|---|---|---|
| Windows | Bitdefender advertises a free antivirus product on its regional product pages. | Bitdefender free antivirus, Mexico or Bitdefender free antivirus, Australia |
| Android | Bitdefender Antivirus is a free app with on-install and on-demand scanning; the listing presents Mobile Security as an upgrade. | Google Play: Bitdefender Antivirus |
| iPhone and iPad | The reviewed US App Store listing is for Bitdefender Mobile Security and describes premium protection with a limited free trial. | Apple App Store: Bitdefender Mobile Security |
Regional availability and terms can differ. For Windows, start with the official Bitdefender site for your country and confirm that the free product is still offered there. The linked Mexico and Australia pages illustrate regional listings, not a guarantee that the same offer applies everywhere.

How to install the Windows or Android app
Windows
- Open Bitdefender’s official site for your region and find its free antivirus product page. Check that the page offers the product in your country.
- Use the download or install option on that page and follow the on-screen instructions. For platform-specific guidance, see Bitdefender’s installation guide.
- Follow any setup prompts shown for the product you downloaded. The installation and activation steps in Bitdefender’s general guide may cover subscription products and should not be assumed to apply identically to every free product.
Android
- Open the Bitdefender Antivirus listing on Google Play.
- Install the app from Google Play, then open it and follow its setup prompts.
- Use its on-install and on-demand scanning features as described in the store listing. Consider Mobile Security only if you want the additional capabilities offered as an upgrade.
Does Bitdefender offer an official APK download?
APK is the file format used to package Android apps; it is not a separate Bitdefender product. The official routes established here are Google Play and Bitdefender’s installation instructions. They do not verify a direct official APK download, so avoid third-party APK download sites and install through Google Play instead.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Is Bitdefender Antivirus Free available for iOS?
The reviewed US App Store page is for Bitdefender Mobile Security, not the same free perpetual product listed for Windows or Android. It describes premium protection with a limited free trial. That listing does not establish that a free iOS antivirus product with ongoing access is available.

Check compatibility before installing
Bitdefender’s general consumer requirements page lists these minimum platform versions for its security apps:
- Windows 7 with Service Pack 1, Windows 8.1, Windows 10, or Windows 11
- Android 6 or later
- iOS 13 or later
These are general requirements covering multiple products, not proof that each product is offered free on each platform. Check the current product page or app-store listing for the app you intend to install, and consult Bitdefender’s system requirements for the broader requirements.

When a trial or paid product may be relevant
If you need more features than the free Android app provides, its listing presents Mobile Security as an upgrade. For broader paid coverage, Bitdefender describes Antivirus Plus as a multi-platform product with a 30-day trial. Its regional trial page also lists a trial period for Android Mobile Security. Plans, trial terms and availability can change or vary by region; check the current Antivirus Plus page and trial page for the offer in your location.
