Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.

What is Choda ransomware? And how does it carry out its attack?
Choda ransomware is a new variant of the infamous Jigsaw ransomware. This new Jigsaw variant was recently discovered this first week of July 2018. Apart from the ransom note and the extension used which is .choda, nothing much has changed in this new malware strain. Based on its ransom note, it seems to target Korean-speaking users. And once it has managed to infect a targeted PC, it will begin to carry out its attack by adding more malicious files to help it in executing some tasks in the system which keeps the crypto-malware undetected by any programs, specifically, antivirus programs installed. It may also create and modify some entries in the Windows Registry. This allows it to run on every system boot.
Once all the changes made are applied, Choda ransomware will scan the entire drive of the system to look for its targeted files. It then starts the encryption using a strong encryption algorithm and appends the .choda extension on each one of the compromised data. After the data encryption, it releases a text file which contains the ransom note written in Korean that reads:
“주확톤 당진희 침퓨터가 지짐각하계 존쟝되었줄끄띠토

Here’s a rough English translation of the ransom note via Google Translate:
“Dangjin of the State of the week, we will be in the summer, John Jean!
Your precious files have been infected by the Mall of Jorda Ransomware
Now you can revert the distant files that follow my directives.
All of the files are encrypted and can not be accessed.
This ransomware is based on the Pode encryption method molar.
Therefore, there is no sense in changing the extension drive.
The file extension cannot be reversed even if the directive is changed.
Do not close this long sound or turn off the computer, rules.
If this is closed or the computer is shut down, the rule is “kite”
I’ll erase the files again.
Please do not use any other company’s extreme luxury pictures except this program.
While other other extreme glamorous prawns, the file cannot be reversed.
From now on, things are simple.
Just enter the space below here, the ultimate security code, and the dramatization will proceed.
Please do your best”
