How to remove Juwon ransomware

Juwon ransomware is a virus that fails to encrypt files but still demands ransom payment

Juwon ransomware is malware that was first discovered in mid-January 2019. The virus spreads with the help of malicious sites, repacked software, fake updates,^[1] spam emails, and other distribution methods. As soon as the payload is executed, malware launches a ransom note called “jw ransomware.” It claims that victims' personal files have been encrypted using AES encryption algorithm and asks them to enter a password that costs 10 BTC. However, Juwon ransomware is a fake cryptor, which means that it does not affect files in any way. The main executable of the virus is juwonRansomeware.exe (hence the name), although the developer Seojuwon, who is believed to be from Korea, calls the malware jw ransomware.

Juwon ransomware is a small-scale virus that affected just a few users so far. Luckily, the virus does not encrypt files, so all users have to do once infected is to remove Juwon ransomware from their machines without major consequences.

The ransom note states the following:

Explanation
Sorry. The computer is encrypted by a military level algorithm by jw ransomware and can not be accessed. To recover you must enter your password or purchase a decryptor. The moment you close this program, your computer will be a fool. Seojuwon is a computer genius. Failure to enter the password within 24 hours will destroy the computer. Typing juwon will display a password hint. And when you give up, your computer is instantly destroyed.

Payment Method: Purchase Bitcoin 10 and send it to this address, or buy the voucher and send the code to seojuwon0622@gmail.com

It is evident that Juwon virus author is not a native English speaker, and the whole ransom note looks quite ludicrous. All the promises of “destroyed” computer are effectively fake, as is the file encryption. Therefore, there is no need to contact the Juwon ransomware developer via the seojuwon0622@gmail.com email address and, especially, pay the ransom of 10 BTC (which is 35,870 USD at the time of the writing).

Regardless of how unfunctional the malware is, Juwon ransomware removal should not be delayed. The developer can improve the malicious code at any time, and then update it, turning it into a fully functional cryptovirus. 

To eliminated Juwon ransomware, users should rely on security software that can detect the malicious file. Additionally, we suggest users run a scan with FortectIntego to repair the computer after the initial damage done by juwonRansomeware.

Ransomware distribution methods and intrusion prevention

Bad actors typically employ multiple distribution techniques in order to infect as many devices as possible. The reason is simple: the more infections, the more probability of users paying the demanded ransom. Unfortunately, users are often oblivious when it comes to the calls of cybersecurity experts^[2] about dangers of malware. They often fail to use adequate security measures and end up permanently losing their personal files and even ransom money.

Therefore, when browsing the internet, you should/should not:

• Download and install powerful security tools that would be able to prevent most of the incoming malware;
• Prepare backups of your files systematically to be able to recover from ransomware attack;
• Spam emails are often used to propagate a variety of viruses, and macro-enabled documents or hyperlinks can instantaneously lead to the infection. Thus, only open attached files or click on links if you are sure that the email is legitimate;
• Do not download cracks, keygens, codecs, and similar tools;
• When using Remote Desktop Protocol, apply a strong password and use a VPN service. This will prevent attackers from using brute-force^[3] attacks;
• Patch your software as soon as updates are out.

Remove Juwon ransomware with the help of security software and then proceed with file recovery

Even if Juwon virus does not encrypt files, the infection is genuine and poses a threat to cybersecurity. Therefore, it is vital to perform Juwon ransomware removal as soon as possible. We recommend using reputable security tools that could detect and eliminate the threat automatically.

If you try to remove Juwon ransomware manually, you might damage your Windows operating system files by accident, which would make matters much worse and would force you to reinstall Windows entirely. Therefore, rather keep the procedure safe by using security software.
