This page aims to help you remove KCW Ransomware for free. Our instructions also cover how any KCW file can be recovered.

In the following, lines we have explained for you some essential insight about KCW. In addition, we are going to share some essential facts about the malevolent software group this program belongs to – the infamous Ransomware virus category.

To say it clearly and briefly – the malware from this category is usually used for file encryption. This means that such a virus normally makes it impossible for you to reach certain files on your computer. KCW, as a version of Ransomware, makes no exception and could do exactly the same. One more common aspect of this kind of malware is the generation of a frightening ransom-requesting message that informs the user about the demanded money payment. Its basic goal is to notify you about the encryption process and the fact that your files might be lost forever in case you refuse to pay the money the hackers demand from you.

What is Ransomware all about?

What all Ransomware versions can do is encrypt something on your machine. By encoding some data we mean making it inaccessible to you. Right after the process of encryption has been fully conducted, you are going to be informed about all that by the generated ransom-demanding alert.

In the coming paragraphs, we will explain everything about the elements of your system that are indeed at risk of being affected by Ransomware. What is more, we will be talking about all the versions of this malicious software and its most common sources. Also, we are going to share with you some great and very important prevention tips as well as some possibly effective removal steps to help you deal with this threat.

How many subcategories does this malware consist of?

This awful malicious family includes two main virus subtypes that use different methods for blackmailing you. Their typical characteristics are explained below.

  • Ransomware affecting various file formats: This subgroup includes all the Ransomware-based viruses programmed to contaminate your device and prevent you from using some of the files there. When the true encryption process gets started and all of the most commonly used data gets encrypted, the generation of a terrible ransom-requesting alert follows. It serves the purpose of telling you about the harmful activity that has been going on in your machine.;
  • Ransomware affecting screens/monitors: This subcategory involves the Ransomware-like programs that could be used for preventing you from accessing the desktops of your devices (or the screens of your tablets and smartphones). Sincerely, if that is your case, your data shouldn’t be typically endangered. Nonetheless, the access to any file format could be made impossible since the ransom notification itself will stops you from using your device. Obviously, the demand for a ransom will still be present, however, this time in the ransom will be wanted in exchange for the access to your screen, not to the actual files.;

How to Decrypt KCW files

We have a comprehensive (and daily updated) guide on how to decrypt your files. Check it out here.

KCW is a representative of:

  • The file-encryption related Ransomware subcategory that is the first one we have talked about above. This is the worst possible case as some of your sensitive, work-related data could be in danger because of KCW.

The most commonly used sources of a virus such as KCW:

All types of content that is online could be contaminated by Ransomware and  may carry such malware. Despite that, there are some sources that are used more often than others:

  • Email letters that are spam: Each shady-looking email sent to you could be carrying viruses like KCW (or other versions of Ransomware). We recommend you never open the ones you have not really expected (or the ones with unknown or questionable content). Also, make sure to stay away from all shady attachments (like some odd-looking .exe files, documents and images).;
  • Malicious advertisements: The method of Malvertising is one more major source of Ransomware. It allows the spreading of pop-ups and other kinds of ads that could be able to redirect to possibly infected web platforms and other malware sources.

What is the solution to such a serious issue then? Removing KCW:

Sadly, there is no really concrete, always-effective solution against Ransomware and KCW after the infection has already been conducted.

In spite of that, it is good for you to get some special software or contact a nearby expert for help. What is vital is to always seek alternatives instead of directly making the ransom transaction. We have offered you one such possible solution down below – a removal guide manual for KCW. Make sure to give it a try if the malware has infected your computer.

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!
