What is Pr09 ransomware?

Pr09 is a cryptovirus that can restrict access to multiple files that are located on a Windows computer. This is done to be able to blackmail victims of the virus with the purpose of money extortion. Once infected, it starts scanning the system for pictures, videos, documents, databases, archives, and other personal files that may be of value to the user. Afterward, they will all be encrypted so that they will become inaccessible until a ransom is paid. However, we still do not recommend you to do this, because it may lead to a scam or a second virus attack. Instead, you may use our guide in order to remove Pr09 ransomware and decrypt .pr09 files.

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 to 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 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, invasion of your personal life. Now the antivirus protection is so huge that it is difficult to make a choice in favor of one of them.
