Cezar virus Removal Guide
Description of Cezar ransomware
Developers of Dharma virus present new crypto-malware – Cezar ransomware
Cezar ransomware is a new version of a Dharma virus that usually enters the system via malicious spam email and encrypts files using the sophisticated cipher. During data encryption, it locks files with .cezar or .cesar file extension and delivers a short ransom note in HELP.txt file.
The updated version of Dharma barely differs from the original malware. It seems that the only significant change is a new file extension to targeted files. Cezar virus aims at PDF files. MS Office documents, virtual drives, various types of pictures, audios or videos. Security experts suspected that ransomware uses AES encryption to corrupt the files. Besides, it appends a long and informational extension:
The ransom note is short. Hacker just asks to send him (or her) an email to firstname.lastname@example.org and learn about data recovery possibility. There’s no doubt that victims are asked to pay the ransom. However, it's not sure how much. Though, this method is not reliable and might end up with an even bigger loss.
Unfortunately, Cezar removal won’t help to get back access to your files as well. The virus might delete Shadow Volume Copies, so using third-party decryption tools might not give the best results. However, some of the Dharma decryption keys might were leaked and some versions of malware are decryptable. Thus, this decryption software might updated soon. Just be patient!
Getting rid of the virus quickly is important because crypto-malware makes numerous changes to the Windows OS. It might alter Windows Registry entries, block computer’s security, delete or modify other system processes. Thus, using a computer infected with Cezar malware is not safe.
The only safe way to remove Cezar without causing any problems to the system is employing security software. We recommend for this task ReimageIntego. The instructions how to disable the virus and run anti-malware is given at the end of the article.
Cezar ransomware virus delivers a ransom note as soon as data encryption is over.
The analysis of ransomware distribution methods
Cezar ransomware might be spread using various strategies and methods, such as:
- malicious spam email attachments,
- bogus security software downloaders,
- fake updates,
- spam websites,
- game cracks,
- key generators.
As you can see, there are numerous ways how ransomware can enter the system. However, malicious spam emails remain the main distribution method. Social engineering helps to trick users into opening obfuscated Word documents and looking for important content.
Researchers report that this version of Dharma spreads via Macro-enabled Word documents. Thus, in order to launch the attack, users have to click “Enable Content” button. However, you should never open any files sent from unknown senders.

How to prevent from getting ransomware
Prevent the government from spying on you
As there is a growing debate in government about collecting users' data and spying on citizens, you should take a closer look at this issue and find out what shady ways of gathering information can be used to collect information about you. You need to browse anonymously if you want to avoid any government-initiated spying and tracking of information.
You can enjoy secure internet browsing and minimize the risk of intrusion into your system if you use Private Internet Access VPN program. This VPN application creates a virtual private network and provides access to the required data without any content restrictions.
Control government and other third party access to your data and ensure safe web browsing. Even if you do not engage in illegal activities and trust your ISP, we recommend being careful about your security. You should take extra precautions and start using a VPN program.
Recover files damaged by a dangerous malware attack
Despite the fact that there are various circumstances that can cause data to be lost on a system, including accidental deletion, the most common reason people lose photos, documents, videos, and other important data is the infection of malware.
Some malicious programs can delete files and prevent the software from running smoothly. However, there is a greater threat from the dangerous viruses that can encrypt documents, system files, and images. Ransomware-type viruses focus on encrypting data and restricting users’ access to files, so you can permanently lose personal data when you download such a virus to your computer.
The ability to unlock encrypted files is very limited, but some programs have a data recovery feature. In some cases, the Data Recovery Pro program can help recover at least some of the data that has been locked by a virus or other cyber infection.
