How to remove SYSDOWN ransomware

SYSDOWN ransomware is still under development

SysDown is a file-encrypting virus which was first released by Royal for testing purposes only. After data encryption, it appends .sysdown extension at the end of the file-name. However, it seems that malevolent people might exploit the malicious program for making illegal profits.

Currently, SysDown is in-development stage since its ransom note appears to be unfinished. The message only claims that the computer was infected with the ransomware. The information about the demanded amount of the ransom or contact details is not provided.

Despite the fact that SysDown ransomware is now under development, there is a strong possibility that the criminals will start distributing it online. Likewise, if you have been already infected with this computer threat, immediately take appropriate measures to protect your system from further damage.

Learn how ransomware can reach your system

Even though this malicious program was not initially distributed to infect innocent people, hackers might spread the updated version online. Since a vast of people keep on paying the ransom, criminals are motivated to release upgrades or new variants of the file-encrypting viruses.

They might distribute it with the help of spam emails which hold the malicious attachment inside. Usually, they look incredibly similar to the ones sent by legitimate companies. In fact, hackers imitate that they come from well-known brands, etc. Likewise, people are convinced to open the infected file which is attached to the email and infiltrate ransomware.

Also, another popular way to distribute file-encrypting viruses is to place them on peer-to-peer (P2P) networks where people come to seek for illegal downloads^[2]. Criminals create a misleading appearance of a legitimate software/update as Adobe Flash Player which actually hides a ransomware executable inside. 

Thus, we strongly advise you to avoid clicking or downloading the content which might be potentially malicious. Always double-check whether the received email corresponds to your recent activity and do not open it if you do not recall having business with the sender. 

Additionally, do not download video, audio or other files illegally. If you do so, note that you have no guarantees that the file will not be malicious. Likewise, we suggest installing applications only from verified developers or official distributors. This way, you will protect your PC from potential hazards.
