Meduza virus

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. This ransomware-type virus has the same operating principle as hundreds of other ransomware, so it encrypts files and adds .[].meduza or similar extension to mark data which can't be opened or used. 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.

To encrypt target files, the virus is using an AES algorithm[1]. Due to its unique functionality, it is almost impossible to decrypt damaged data, even if you are a true tech expert. Typically, the decryption key is stored on a remote server and can only be reached by its owners.

No matter how hard it seems to lose your images, business documents, and similar data, we do not recommend paying the ransom as it usually turns out to be a trick to swindle the money from naive victims. Beware that cybercriminals often leave users scammed as soon as they receive their money.[2] As an alternative, you should remove Meduza ransomware from your computer system and then use one of the data recovery methods provided at the end of this post.

Distribution of the ransomware spreading and avoiding techniques

According to IT professionals[4], the most common way for this ransomware-type virus to enter the system is related to spam. These kinds of messages come with a harmful attachment which is already included in the email message as an important document, such as invoice, an image, etc. However, once opened, the virus is activated and starts its damaging activity. 

To avoid serious ransomware infections, follow these guidelines:

  • If you receive any suspicious email, you need to double check it before opening. If you have any doubts, you should better eliminate the email for your safeness. Do not get tricked by shady and dubious senders.
  • Try to avoid visiting suspicious-looking sites and links. Once entered, they might try to initiate infiltration of a ransomware-type virus behind your back.
  • Consider installing a professional security tool. An antivirus will protect your system, scan it, and alert if some harmful components are trying to infect your PC.

Do not let government spy on you

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
