Dealing with this infection requires a systematic approach to ensure the virus is gone and your data is handled safely. Step 1: Isolate the Infected System

Use reputable tools like Malwarebytes, Emsisoft, or Windows Defender. These programs are effective at identifying and deleting the core STOP/Djvu registry keys and executable files.

If the ransomware used a unique online key, decryption is currently impossible without the hackers' private key. Paying is highly discouraged, as it funds criminal activity and provides no guarantee of file recovery. Step 4: Alternative Data Recovery If a decryptor doesn’t work, try these "Plan B" methods:

If the virus didn’t delete your Shadow Copy backups, this tool can revert files to their previous state.

If the ransomware couldn’t connect to its server during infection, it used a generic "offline key." These can often be decrypted using the Emsisoft Decryptor for STOP Djvu .
