I am Karsten and will gladly help you with any malware-related problems.
Please familiarize yourself with the following ground rules before you start.
Read my instructions thoroughly, carry out each step in the given order.
Do not make any changes to your system, or run any tools other than those I provided. Do not delete, fix, uninstall, or install anything unless I tell you to.
If you are unsure about anything or if you encounter any problems, please stop and inform me about it.
Stick with me until I tell you that your computer is clean. Absence of symptoms does not mean that your computer is free of malware.
The file extension .pezi has been used by STOP/DJVU ransomware. STOP ransomware variants after August 2019 are only decryptable if an offline key was used. Most of the time this is not the case, though.
Please upload an encrypted file and a ransom note here to confirm that it is indeed STOP/DJVU ransomware.
