You can infect PC by downloading some pirate programs, clicking on suspicious pop-ups with fake “update” links and via emails. Be really careful before clicking on some attachments and running programs from an unknown source.
When it infects your PC it will scan all files and encrypt them with WNCRY extension. Access is blocked to images, documents, and music, and system files. After that, you will see the message on the screen “Oops, your files have been encrypted” and demand to pay $300 in Bitcoins to decrypt your files. However, no one guarantees that after paying the ransom the files will be decrypted.

To ensure that this epidemic bypasses you immediately need to install the patch MS17-010 from Microsoft. After installation, restart the computer. You need to scan your PC and in the case of detection of malicious attacks (Trojan.Win64.EquationDrug.gen) – reboot the system again and make sure that the patch MS17-010 is installed.

If you are already infected follow steps below to eliminate the virus.

  1. It is necessary to enable the safe mode with the network drivers loaded.
  2. Then you need to scan the system with a strong antivirus program and remove all detected files

The final step for the user is to restore the encrypted files, you can only do this after Wannacry is uninstalled. Otherwise, system files and the registry can be damaged. For this, you can try different decryption programs, but they don’t guarantee to restore files.

So as we can see viruses don’t sleep and are evolving every day. WannaCry will definitely be on our next list of the top 10 viruses.
