May virus Removal Guide
What is May ransomware virus?
Month of May marked with an emergence of May ransomware
May virus is a cyber infection which uses a strong encryption algorithm to render victim’s personal files useless. In the technical terms, it is called ransomware . The chronology of the attack is simple. First, the virus infiltrates computers and runs the encryption process during which it encrypts files using AES-256 and RSA-4096 algorithms and appends them with .locked extensions. The duration of this process may vary depending on the amount of data that is being processed. Then it drops a text file called Restore_your_files.txt on every folder that contains encrypted files. As you can probably guess from its title, this document features all the necessary information about how to restore the data. In particular, the victims are pushed towards paying the criminals 1 Bitcoin  and contacting them via firstname.lastname@example.org email address for further instructions. The victims are only given 5 days to make the payment. Unfortunately, even when the money is transferred, the criminals rarely get back to the victims. More often, they simply flee with the money, leaving victims to deal with a corrupted system by themselves. Besides, the hackers may program the virus to block antivirus software installed on the device and this way prevent May virus removal. Luckily, there are a few ways to bypass this obstacle, and our experts provide them below this article. You will fix your computer easily by scanning it with a reputable antivirus tool such as ReimageIntego.
If you are wondering how the whole ransom payment process is orchestrated, just take a look at the ransom note this virus leaves on the computer more closely. Here is a transcript of this text file:
You have 5 days for decrypt your files.
All your files have been encrypted with May Ransomware.
For encrypt we use AES256+RSA4096.
Don`t try recover your files.
1) Make your bitcoin wallet on block.io or blockchain.info and buy 1 bitcoins on BTC Exchange Sites (https://goo.gl/1PE96T)
2) Send 1 bitcoin to address 3Gw6b57A3E34nAph3mzGbKAj8sTSgD8GP9
3) Write to us on email email@example.com . In subject write this identificator “81ff05bf2ab1406d8f11b866e804af37”
4) After receive bitcoins and your email , we contact with you.
YOU MIGHT DECRYPT 2 FILES FOR FREE. Send it to email firstname.lastname@example.org .In Subject ,write your UNIQUE Identificator.
As you can see, the criminals provide each of their victims with a personal identification number. Presumably, the hackers keep all the ID’s in some sort of database next to the unique data decryption keys. That’s why the victims are asked to submit this number along with the payment. Nevertheless, this does not mean that you should. On the opposite, you should avoid getting involved in any type of collaboration with the criminals and take all measures possible to remove May virus from your computer.
May ransomware infiltrates computers just to lock the containing files and to demand victims for a ransom.
Let’s expose some of the ransomware distribution strategies
Typically ransomware creators try to remain very discrete about the ways they distribute their evil products around, to avoid having these malicious networks shut down. Nevertheless, over the years of research, experts have already exposed quite a lot of techniques ransomware developers use to deploy the malicious encryptors on the victim’s computers. We now know that most ransomware travel via malicious spam campaigns. Others rely on deceptive software update advertisements, while the most malicious ones like, say, WannaCry virus apply exploits to brute force their way into systems. May ransomware may not be using the most sophisticated techniques, but like most ransomware, it is always open to various adjustments and modifications. So, you have to be careful and make sure you take all measures to prevent May from accessing computer.

How to prevent from getting ransomware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
