Malwarebytes Freeは、WindowsやMacでは主に必要なときにスキャンして脅威を除去するための無料ツールです。有料版のように常時監視して攻撃を防ぐ製品とは役割が異なります。Android、iPhone、iPadでは使える機能も異なるため、「無料アンチウイルス」の内容は端末ごとに確認してください。

Malwarebytes無料版でできること

Malwarebytesの公式ダウンロードページは、無料版を「サイバー攻撃ですでに被害を受けた端末をクリーンアップするツール」と説明し、Premium Securityは攻撃を未然に防ぐものと区別しています(公式ダウンロードページ)。つまり、無料版は手動スキャンや感染後の確認・除去を中心とし、有料版の継続的な保護と同じものではありません。

以下はMalwarebytesの機能比較表(2026年9月8日更新)と日本語の製品ページに記載されたベンダーの機能説明に基づきます。独立した検出率試験の数値を示すものではありません。機能の提供状況はOSや地域によって変わる場合があります。

Windows・Macではスキャンと継続保護が分かれる

公式比較表では、WindowsとMacのQuick Scan(クイックスキャン)およびCustom Scan(カスタムスキャン)は無料、Threat Scan(脅威スキャン)は有料とされています。Windowsのスケジュールスキャンも有料扱いです。リアルタイム保護、Web保護、マルウェア保護も有料機能です(公式機能比較表)。

Elebase USB to USB C Adapter for iPhone 18 Pro Max,USBC Car Charger Adapter
  • Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
  • Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
  • Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
  • Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
  • 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.

この区別は、感染が疑われたときに自分でスキャンしたいのか、日常的に脅威を監視・遮断したいのか、という選択に直結します。無料版を導入しただけで、常時保護や危険なWebサイトの遮断まで有効になるとは考えないでください。

Android・iPhone・iPadの無料機能

モバイル版は「スマートフォンなら無料で同じ保護」と一括りにはできません。日本語の製品ページでは、Android向けにスキャン・削除とアプリのプライバシー監査、iOS向けにSafariの広告ブロックとテキストメッセージのフィルタリングを案内しています(日本語の無料アンチウイルスページ)。

無料版と有料版を選ぶ目安

  • 無料版が合う人:必要なときに手動でスキャンしたい、感染後のチェックやクリーンアップを目的としている。
  • 有料版を検討する人:リアルタイム監視、Web保護など、端末を継続的に守る機能が必要。
  • モバイルで使う人:Android、iOS、iPadOSのどれかを確認し、希望する機能がそのOSの無料枠か有料枠かを比較表で確かめる。

有料プランはStandard、Plus、Totalなどに分かれ、VPN機能やデータ・サーバーの利用条件もプランによって異なります。契約前に公式比較表で対象OS、保護機能、VPNの条件を照合してください。日本向け価格は、掲載時点で確認できる購入画面の金額を参照してください。ここで根拠のある固定価格は示せません。
