対応方法
手順 1
Windows 7、Windows 8、Windows 8.1、および Windows 10 のユーザは、コンピュータからマルウェアもしくはアドウェア等を完全に削除するために、ウイルス検索の実行前には必ず「システムの復元」を無効にしてください。
手順 2
このマルウェアもしくはアドウェア等の実行により、手順中に記載されたすべてのファイル、フォルダおよびレジストリキーや値がコンピュータにインストールされるとは限りません。インストールが不完全である場合の他、オペレーティングシステム(OS)の条件によりインストールがされない場合が考えられます。手順中に記載されたファイル/フォルダ/レジストリ情報が確認されない場合、該当の手順の操作は不要ですので、次の手順に進んでください。
手順 3
Windowsをセーフモードで再起動します。
手順 4
コンピュータを通常モードで再起動し、最新のバージョン(エンジン、パターンファイル)を導入したウイルス対策製品を用い、「Ransom.Win32.THANOS.THABGBB」と検出したファイルの検索を実行してください。 検出されたファイルが、弊社ウイルス対策製品により既に駆除、隔離またはファイル削除の処理が実行された場合、ウイルスの処理は完了しており、他の削除手順は特にありません。
手順 5
以下のファイルを検索し削除します。
- %User Temp%\RESTORE_FILES_INFO.txt
- {Encrypted directory}\RESTORE_FILES_INFO.txt
- %Desktop%\RESTORE_FILES_INFO.txt {Teslacrypt_note.png}
- %User Startup%\mystartup.lnk
手順 6
暗号化されたファイルをバックアップから復元します。
