The item is dedicated to ransomware called MoonCrypter which penetrates users' computers in diverse countries of the world, and encrypts their data. Here you can find important information on MoonCrypter's essence, and how to uninstall MoonCrypter from your laptop.

MoonCrypter ransomware already penetrated many computers in various countries through most effective manner: scam messages with viral attachments. Sometimes web-criminals use zero-day vulnerabilities to take control over the computer, but big program vendors quickly fix them. When infection is done, the virus examines the hard drive, defines the number of folders for encryption and their general price. Currently, any new virus can cypher image, video, audio and text files in all known extensions. MoonCrypter cyphers all files, but those that look like business documents go first. MoonCrypter encrypts only files with information, and doesn't touch the programs, so that the man can use his PC to make the payment. Encryption is made with the help of well-known AES and RSA algorithms, and its intricacy is so high that decipherment of information with no key is impossible. Such complexity is the reason for impressive success of ransomware in recent years: common user, even having a pretty good experience in suchlike things, won't ever get back the files, and will have no way out except paying to scammers. The only method to decrypt files is to crack the scammer's site and withdraw the encryption keys. Some skilled hackers can get the keys via defects in viruse's program code. The encrypted files acquire .cmoon extension.

The computer knowledge is highly important in our world, since it helps customer to protect the machine from harmful software. For ransomware this is most important, because, in contradistinction to common viruses, after uninstalling ransomware from the system, the effects of its actions will stay. To defend yourself, you need to remember a three simple principles:

    • Closely inspect your emails, particularly those messages that have attached files. If you don't know the user who send an e-mail and it is about winning some prize, a lost parcel or anything like that, this might be ransomware. Also you should be attentive with business correspondence, especially if you don't know the sender and not sure what's inside. appeals, lawsuits, summaries, Invoices for services and goods and suchlike specific information cannot come without warning, and you, as a minimum, should know the person who sent it. In all other cases it is a fraud.
    • Don't disregard the red flags that your PC shows. File encrypting is a complex process that requires a lot of PC resources. If you observe a strange decrease in workstation performance or see a unknown string in the Process Manager, you can switch off the workstation, start it in safe mode, and scan for threats. This, in case of infection, will guard some of your files.
    • Take notice to the pop-ups. If the computer is infected by ransomware, it will try to delete all copies of the files, to make the recovery less possible. Anyway, removal of copies requires admin rights and your acceptance. If you'll think for a moment before confirming the changes, it might save your files and your money.
