CSP ransomware. How to remove? (Uninstall guide)

removal by Jake Doevan - - | Type: Ransomware

CSP ransomware is the cryptovirus that locks users' data with the AES encryption algorithm and demands payment in Bitcoin cryptocurrency

CSP ransomware
CSP ransomware is the virus that encrypts users' data and makes those files no longer accessible.
 

CSP ransomware is the virus that gives 48 hours for the victim to pay up for the decryption key. Unfortunately, this decryption key is the bait for victims used by cybercriminals who focus on getting money from them. The amount of ransom these people demand depends on the number of affected files or the value of this data. However, you should focus on malware elimination and worry about data recovery later because the main danger is the CSP ransomware virus that encrypts and marks your files using .csp appendix and can alter more severe parts of the system. All the information about this ransomware attack is stated in the ransom note called HOW TO DECRYPT [-].txt which is placed on the system after the initial file locking.

Ransomware-type threats like CSP ransomware starts the attack with a quick system scan, to see if the system was encrypted already or not. Then various files in common formats like photos, documents, audio or video files get encoded and locked. All encrypted data gets a file marker _csp, hence the name if the ransomware.

When your files get encrypted and locked by CSP ransomware virus, you should immediately notice a text file added on the desktop and possibly in every folder that contains affected files. This ransom message is called HOW TO DECRYPT [-] .txt and the brackets contain identification number also included in the not itself.

CSP ransomware is the cyber threat that focuses on file locking and ransom demanding because the primary purpose of the people behind this virus is to get money from data owners and gain a profit. Take this into consideration when you think about paying the ransom because your files are not important for these criminals and they may disappear after the transaction.[2]

There is no clear relation with other crypto malware threats, but CSP ransomware is a typical cryptovirus that besides the file encryption can:

  • alter Windows registry entries;
  • add startup files;
  • disable functions;
  • install programs or data;
  • keep security software from working properly.

Based on all these functions, people should be already eager to remove CSP ransomware. However, it is not an easy procedure when your data or even private information is at risk. Virus termination process, especially when it comes to dangerous ransomware takes time and requires professional help.

The best tip for CSP ransomware removal that experts[3] often give is to get a reputable anti-malware tool and scan the device entirely. This way the main payload file can be found and removed. Also, don't forget to further check the machine with Reimage or a similar tool and get rid of virus damage. 

Cryptographers get distributed via spam email

When your antivirus program is not up-to-date or otherwise neglected, it doesn't work correctly, and your device cannot be secured. Often AV engines indicate possibly malicious emails or files when downloaded and can keep your computer safe. However, when you are not paying enough attention yourself, the system gets infected by various malware including ransomware.

Emails with suspicious senders or subject lines should be deleted without reading or opening the attached file because emails often contain Microsoft files like Word or Excel documents, PDFs, or databases. Downloading and opening an infected file on the system leads to direct ransomware payload dropping or malicious script launching. 

In most cases, these files get filled with malicious macros, and the script is triggered when you enable the content of the document. This infiltration happens without your notice, and unfortunately, ransomware gets on the system. Keep your antivirus tools up-to-date to avoid these infiltrations.
