What is Youhau ransomware?

Youhau ransomware is a data-kidnapping ransomware that targets Windows machines. It aims to encrypt personal files on victims’ PCs such photos, movies, papers, databases, archives, and so on. This is typical of most viruses of its sort. Afterward, cybercriminals demand money from victims in BTC cryptocurrency to regain data access. But, even if the cash is made, no one can guarantee that they will deliver you the decryption tool, thus we do not advise you to do this. Instead, you may follow our step-by-step guidelines in order to remove Youhau ransomware and decrypt .youhau files without spending any money.

As we mentioned earlier, the virus affects data in such a way that you won’t be able to open files until they are decrypted. Within encryption, all infected files are appended with a new extension: .(random-characters)(cyberabc@tutanota.com).youhau extension. A little later, Youhau ransomware leaves a TXT file (Dectryption-guide.txt) that urges users to pay a ransom in order to get files back. As usual, cybercriminals offer free decryption of several files to prove that they can really decrypt the victim’s files.

The content of Dectryption-guide.txt:

How to prevent your system from Ransomware?

No one is safe from infection with a virus that secretly encrypts your data. But in order to minimize this risk, you need to follow the rules:

1. Always make Windows updates on time and keep them up to date. Remember that these updates close the security holes in the system through which the virus can enter your computer.

2. The most efficient way to avoid data loss is of course to make a backup of all important data from your computer. It is enough just to synchronize the necessary folders with one of the cloud services, so as not to be afraid to see the text requiring the payment of bitcoins in exchange for a decryption key. It can be a cloud or a remote hard drive on the network. If you store all your files on the Internet, the likelihood of virus infection will be lower. Do not make copies on external hard drives, as this could damage them.

3. Since spam email is the most popular form of spreading ransomware-type viruses, the user should never open email attachments without first having scanned them with an antivirus. Just clicking on the link or opening the attachment can damage the operating system (Windows) in a few minutes, damage important data, and infect other machines with the virus.

4. All previous methods do not matter if you do not have a reliable antivirus. The presence of anti-virus protection on your computer can prevent all these unpleasant surprises. Anti-virus protection will protect you from malware, money loss, time loss, and invasion of your personal life. Now antivirus protection is so huge that it is difficult to make a choice in favor of one of them. If you have not decided who to give preference to, we suggest you familiarize yourself with our Top 5 Antivirus Software for Windows
