.Kuub Virus

The .Kuub Virus will leave this message in a _readme.txt file.

.Kuub is a Ransomware cryptovirus infection that targets personal user files, seeking to encrypt them. If your files have been encrypted by .Kuub, you will immediately notice a ransom-demanding note on your screen.

Unfortunately, we’re sorry to say that .Kuub is one of the most hazardous viruses out there. It’s a Ransomware cryptovirus that encrypts the files on your computer, making them unavailable to you, and then offers to give you the key for decryption in exchange for a ransom payment. Sadly, removing the virus (which you should most definitely do!) won’t help you restore those files – they’re going to stay encoded unless you apply the correct decryption key. In this guide, however, we will give you step-by-step instructions on how to remove .Kuub, and how to recover some of your files without having a decryption key.  

The .Kuub virus

.Kuub is a computer virus of the notorious Ransomware variety. A ransomware virus such as .Kuub would encrypt your files and demand a ransom payment in exchange for the decryption keys.

The .Kuub virus is very malicious software piece, which belongs to the Ransomware cryptovirus category. One of the most common ways in which the .Kuub virus can infect more systems is by using a malicious email attachment.

The victim will usually receive an email message containing either an infected file (this can be any file), or a link to a certain website. The Ransomware will be automatically downloaded to your computer after opening the file, or following the included link. Unfortunately, there’s little to no way to detect its presence, since this malware does not show visible symptoms.

If .Kuub succeeds in its malicious operation, it will inform you about the encryption that has taken place, usually through a message shown on your screen. The message will let you know that your files have been encrypted, and will tell you to send money to a given cryptocurrency wallet in exchange for a special decryption key. Typically, you’d be threatened that the required sum would double or triple if you do not pay soon. This is done in order to put some pressure on you, and discourage you from searching for alternative solutions to the ransom payment.

The .Kuub file encryption

.Kuub is a ransomware type of a computer virus. .Kuub is a very dangerous file encrypting malware that would cripple a user’s computer and demand a ransom payment in the form of Bitcoins.

The .Kuub file encryption is a big issue, and dealing with it may not be easy. Even after you remove the Ransomware, the .Kuub file encryption may not be reversed unless the correct decryption key is applied.

By paying the hackers, however, you will only ensure that they have the right motivation to continue with their blackmailing schemes. And with that in mind, here’s another thing to consider – people who go about hacking into the computers of other people, and extorting money from them shouldn’t really be trusted. There is no guarantee that they will send you that key they talk about, or that it will work. That’s why we suggest you don’t rush to pay them, and instead first try the steps in the guide below.

We can also recommend just a few simple but effective tips to keep your computer safe from Ransomware in the future. Needless to say, you should always keep a good antivirus program in the computer – one that has detection for Ransomware. Also, avoid opening emails from suspicious senders, particularly if they include attachments. And if you have opened one such message, please, do not hurry to download the attached file(s), or to click on the hyperlink, if there is one. You should also try to stay away from any obscure websites that could potentially hide viruses like .Kuub.
