Malwarebytes Inc.
Malwarebytes Download
The cleanup tool that became a full antivirus — with a free on-demand scanner.
What the Malwarebytes download actually is
Download Malwarebytes only from the developer. Mirror sites repackage installers with adware more often than most people expect.
Scans are fast because the engine targets specific threat classes rather than exhaustively hashing every file. Premium's real-time layer is light.
Step by step
- 1. Download only from malwarebytes.com.
- 2. Install — you can keep your existing antivirus, the free scanner is designed to coexist.
- 3. Update the database, then run a full scan.
- 4. Quarantine everything it finds, reboot and rescan to confirm the machine is clean.

Frequently asked questions
- Is Malwarebytes free antivirus?
- The free download is an on-demand scanner and remover, not an always-on antivirus. Real-time protection is part of Malwarebytes Premium.
- Can I run Malwarebytes free alongside another antivirus?
- Yes. Because the free version is not resident, it does not conflict with Microsoft Defender or a third-party suite.
- How do I run a free Malwarebytes scan?
- Install the free version, click Update, then Scan. A full scan on a typical PC takes a few minutes to half an hour.
- Does Malwarebytes remove trojans?
- Yes, it removes trojans, adware, spyware, browser hijackers and many potentially unwanted programs. For a deeply compromised system, also run an offline scan from Windows Security.
