Kimsuky Malware


Kimsuky is a very malicious computer virus that can secretly steal sensitive data and take full control of critical system processes and tasks in your computer. Security professionals classify Kimsuky as a Trojan Horse that is reported to fool their victims with various cover up infection strategies.


Multiple VirusTotal scanners detect the Kimsuky malware.

Typically, such a Trojan threat will be disguised as a harmless application or software that is available free of charge on some low-quality or pirated site. Of course, it’s never a safe idea to download material from such web pages, firstly because it’s illegal, and secondly because this may increase the chance of a close encounter with a harmful infection such as Kimsuky, Wup.exe or Presenoker.

Unfortunately, the main issue is that it is quite impossible to really know if a certain piece of software or web content has a Trojan embedded in it since these threats may also distribute via spam messages, different attractive looking ads, pop-ups, email attachments and more.

A stable, up-to-date antivirus software will , of course, help you spot the hidden danger, although this is not necessarily true to new viruses (also known as Zero-Day malware) that have just been discovered. The reason is, most of the antivirus programs rely on their virus database to identify threats and if the given Trojan has not been added to the antivirus’ malware database yet, it may not be detected. In those scenarios, and if you haven’t updated your security tool from some time, the level of protection of your machine may be greatly decreased and the likelihood of detecting new dangers like Kimsuky on time may be greatly reduced. As a result, you may end up being attacked without any clue.

The Kimsuky Malware

A Trojan virus like Kimsuky would usually show no symptoms, but some of its malicious activities still may cause certain issues in the computer that may serves as visible red flags. The unexpected sudden crashes of the system and the introduction of a hideous Blue Screen of Death are some of the most popular signs that your system is infected with the Kimsuky malware.

Other symptoms that could be related to a possible Trojan Horse contamination include various unusual glitches, device slow-downs, file loss or destruction, and various unauthorized adjustments to the configuration of some applications and programs.

Unfortunately, we are unable to give you any specific symptoms that could be linked to Kimsuky because in some cases there might be any while in others there might be serious issues. All this depends on what type of harm exactly the Trojan has been programmed to perform. What we can say for sure is that, once you detect the malware, you should immediately take actions to remove it and not give it a chance to do more potential harm.

The earlier you delete the Trojan from your machine, the more likely it is that there will be no significant harm to your system or the data stored on it. If you need assistance, below you will find a guide with detailed steps on how to remove Kimsuky. If you think you cannot complete the Trojan-removal steps on your own, it is a good idea to use the recommended removal tool, the link to which is attached in the guide.
