How May Ransomware Virus Harms the PC
May ransomware virus is a data locker type of malware that transforms certain data and renders it unusable. So once the malicious payload that starts the infection process is running on the computer, May virus occupies the system and performs various modifications.
It all begins with a file named May.exe sometimes May_ransomware.exe running on the computer. However, if you choose to remove May virus manually, have in mind that the threat creates and drops new malicious files and then deletes the initial infection file making its detection harder. It could even hide its malicious files in legal processes that are currently running on the system. Some files created by May ransomware virus are likely to be dropped in Windows folders:
%USERPROFILE%
%APPDATA%
The next infection stage is a scanning process of all computer drives in search of target file types that May virus aims to encrypt. For the encryption, May ransomware virus is believed to utilize a combination of two strong algorithms – AES-256 and RSA-4096. During the encoding process, May virus is supposed to encrypt images, videos, documents, text files, archives, configuration files, databases and other. Upon encryption, May crypto virus generates unique decryption key that unlocks all enciphered files. They all have appended the malicious file extension .maysomware and their original names may be transformed into a random string of symbols. We do not recommend victims to pay the ransom as there is no guarantee that crooks will send the decryption key as it could be broken or missing at all.
How much is the ransom? It is 1.5 BTC which currently equals to 3289.38 US Dollars. For the final infection stage cyber criminals have created a file called Restore_maysomware_files.html which is dropped on every infected system. The malicious source code of May ransomware virus is designed to modify Windows registry keys and sub keys so the file Restore_maysomware_files.html gets displayed automatically on victims’ screens. The file contains a ransom message that guides victims how to act further to receive the decryption key. What the ransom note of May ransomware virus reads is:
RANSOMWARE
All your files have been encrypted with May Ransomware. For encrypt we use AES256+RSA4096. You have 5 days for decrypt your files. Don`t try recover your files.

In any cases, it is better to avoid contacting them at the shown email and remove May ransomware virus by following the guide below. Once you remove completely the virus, there is a chance to restore .maysomware files with the help of alternative data recovery tools.
The Shadow Explorer method will not be working in this case because May ransomware virus uses the Command Prompt to write the command line:
vssadmin delete shadows /all /quiet
By doing this, it removes all shadow volume copies stored on the infected PC, and they are no longer accessible by Shadow Explorer software. However, there are other ways to recover .maysomware files. Some of them are also included in the consistent step-by-step removal guide below.
How May Ransomware Virus Lands on the PC
The May ransomware payload may be hidden in a file attached to a spam email that seems totally legit. It may also be integrated into a website that once entered starts an automatic download of the payload. So again a spam email or a message on the social media or an ad may present you the malicious link that infects the PC with May crypto virus. In some cases, crooks may bundle May.exe with the installation package of a freeware program.
