Kuus Virus


Kuus is a ransomware cryptovirus that targets most popular file types on the computers of its victims. Kuus encodes these files using a complex encryption algorithm, thus robbing users of access to said files.


The Kuus Virus ransom message

This is all part of virtual blackmail scheme that originated back in the late 80’s and has been going strong since. The idea behind it is that your files are basically held ‘hostage’ by the hackers in charge of the ransomware attack. And in order to ‘free’ them, victim users are required to send a certain amount of money in ‘ransom’. In turn, the way the files are freed is with the help of a special decryption key, which the hackers promise to send as soon as they receive your payment.

However, there are several issues with this deal. For one, there’s no guarantee that you will in fact receive a decryption key, and practice has shown that not everyone does. And for another, the decryption key is unique for each instance of infection. Therefore, it is possible for mixups to occur, and you could easily end up receive the wrong key – which will not do anything to decode your data. Obviously, the criminals don’t do refunds and you can pretty much forget about getting the correct key.

This is why we generally encourage our readers to try and approach this matter using alternative solutions. Unlike what the cybercriminals will have you believe, there are other ways you can potentially regain access to the files that have been locked by Kuus, Repl, Maas or other STOP/Djvu Ransomware. And in the below removal guide, our team has dedicated a separate section specifically to these possible solutions. However, before you attempt any of them, it is vital that you first remove Kuus form your system. This will prevent any further instances of encryption from occurring later on.

The Kuus virus

The Kuus virus is notoriously stealthy and may bypass most antivirus software on the market. This allows the Kuus virus to operate undisturbed, sometimes for hours at a time.


The Kuus Virus encrypted files

The encryption process is often a tedious one, as files are generally encrypted one by one. And if your machine doesn’t have the most processing power, and/or if it’s overloaded with data, the whole malicious act may take very long to complete. This may even result in a significant slowdown of your system, which may sometimes prompt victims to investigate what the reason for it may be. And in such cases, it’s possible to intercept the virus by noticing it in your Task Manager, which should, in turn, immediately prompt users to switch off the computer at once and seek professional assistance.

The Kuus file distribution

One of the keys to preventing an attack like this is being aware of the Kuus file distribution channels. And the two most common ways in which in the Kuus file distribution occurs is with the help of spam messages and malvertisements.

Sometimes a Trojan horse virus may be employed to act as a backdoor, so it may be a good idea to scan your system for malware once you’ve removed Kuus.
