Kirk virus Removal Guide
What is Kirk ransomware virus?
Sci-fi geeks try on ransomware — release the Kirk virus
Kirk virus is a Star Trek-themed  cyber infection which belongs to the crypto-ransomware  category. This essentially means that when this virus infects a computer, it starts scanning it for certain types of files and encrypts them using a complex algorithm. Though such encryption principle is typical to most viruses of this particular category, Kirk cannot be regarded as a completely conventional ransomware. In fact, this malware has hit the internet with a bang as one of the first extortion programs to base its ransom payment system on cryptocurrency other than Bitcoin. In particular, Kirk utilizes Monero — cryptocurrency which has been steadily growing in popularity within the past year and now has a market cap of around 302,294,761 USD . It is unclear why the hackers have picked this particular currency which stands fourth in the global ranking, but such a choice is simply destined to cause confusion among the victims. Even Bitcoins which are the number one cryptocurrency out there are not the easiest item to get your hands on, especially if you are unfamiliar with such payment system and encounter it for the first time. So, it might be that by attempting to be original the extortionists have simply undermined themselves. This may also be the reason why this virus is currently plateauing. Although there are no known Kirk ransomware victims so far, you can never know when the malware is going to burst. That is why we recommend to be prepared for Kirk removal and obtain antivirus software that would manage to weed this parasite out of your system. ReimageIntego is one of the reputable software you should try.
Kirk ransomware virus is a Star Trek-themed infection which uses a lot of the elements from this famous TV show in its setup. You can see an example of Kirk's ransom note in the picture above
The virus draws malware experts’ attention for a number of reasons, and the use of Star Trek themes in its ransom note as well as the utilization of Monero cryptocurrency for the ransom payments are just a few of them. We should point out the fact that the virus disguises itself as Low Orbital Ion Cannons tool  and runs on the infected computers as a loic_win32.exe process. It even fakes LOIC’s notifications to trick users into thinking that this software is initiating on their computers. In the meanwhile, virus scans the computer looking for more than 625 types of files and encrypts them with a public AES key . In addition, every encrypted file will be appended with .kirked extensions while the virus will drop a ransom note called RANSOM_NOTE.txt on every affected folder to instruct the victim how to decrypt them. Of course, the decryption is not possible without the private key. The extortionists deploy an encrypted variant of this key in the file called “pwd” which will be stored on the computer in case the victim decides to pay the ransom. In such a case, the victim is asked to transfer around 1100 dollars in Monero currency to the criminals’ and then send the transaction ID along with the mentioned pwd file to firstname.lastname@example.org or email@example.com email address. When these steps are completed, the criminals promise to supply the victim with special decrypter called Spock which will supposedly unlock the private key stored in the pwd file and allow data recovery. Needless to say, collaborating with cyber criminals is the last thing you should do, so we recommend leaving this option for last. Instead, you can try recovering your files by following free guidelines our experts have provided below the article. If you do not have any important data stored on your computer, simply remove Kirk from your computer and fix this issue.

How to prevent from getting ransomware
Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
