What is Meduza ransomware?
Meduza ransomware – a cryptovirus which is urging victims to pay 0.08 bitcoin for acquiring the decryption key needed to unlock encrypted data
Meduza ransomware - a file-encrypting virus which blocks any access to user's data by using .[email@example.com].meduza extension.
Meduza ransomware is a cryptovirus which typically denies access to important data and requires the specific amount of bitcoin to recover the connection to it.

Additionally, it drops the copy of a ransom note called as How-To-Recover-Your-Files.html which announces that user's files are infected and requires sending a special payment to decrypt this data. Users are urged to contact the cybercriminals via email@example.com. However, the email address, just like the amount of the ransom, might vary.

How to prevent from getting ransomware
Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
