I wrote this article to help you remove One Ransomware. This One Ransomware removal guide works for all Windows versions.

The ransomware industry has proven itself quite lucrative so newer and newer ransomware pieces get developed every day. One of the most recent members of this family is the One Ransomware. One is a ransomware Trojan and it first appeared in April this year. It doesn’t stand out with anything in particular but this doesn’t make it any less dangerous. In fact, ransomware infections are considered the worst possible threat you could encounter online. There is a reason for that. This parasite is going after your money. But unlike other infections which try stealing your financial credentials, ransomware relies on a different technique. It takes something of yours and then blackmails you for its return. Let`s get into details.

Once on your machine, the One Ransomware performs a quick and secretive scan. This way, it locates all of your valuable files. These include pictures, videos, music, documents, presentations and pretty much whatever else you can think of. After it finds them all, the pest encrypts them with a very strong locking cipher (a combination of the RSA and the AES algorithms), thus making them inaccessible to you.

You cannot open any of the locked files without applying the special decryption tool. Moreover, One adds a new file extension to each locked file which your PC is unable to read. This is how the pest turns your data into unusable gibberish. You are no longer able to use any of your files in any way. Trying to rename them or move them into another folder does nothing as well. After the encryption process is over, the infection drops its ransom note. The message is in Portuguese and states that all of your files have been encrypted.

Also, there is a code in the note which you are instructed to send to the [email protected] email address. The hackers also say that once you have sent the code, they will get back to you within 24 hours with detailed payment instructions. Yes, if you want your files back you have to pay. The ransom usually varies between 0.5 and 1.5 Bitcoins ($1,300 to $3,977). Not only is this sum huge but it also doesn’t guarantee you anything. Crooks cannot be trusted and you have no guarantees that they will keep their end of the deal whatsoever. You can easily end up double-crossed with much less money and still encrypted data.

Don’t pay. Don’t sponsor these cybercriminals. They will only use your money for more malware creation and business expansion. What is more, even if they do give you the decryptor once you pay, you still lose. The tool only removes the encryption, not the infection. This means that you could get your data re-encrypted hours after having freed it. Don’t be gullible. You have to remove the One Ransomware from your PC first and then try and recover your data. To do so, use our detailed removal guide at the end of this article.

How does the One ransomware get distributed? One of the most popular techniques involves spam email messages. Hackers attach corrupted documents to seemingly legitimate emails, which they send to victims. If you are not careful and open any message you get without thinking twice about it, you are making it easier for crooks to infect you. Also, One can use the help of a Trojan horse to enter your PC. Trojans provide many systems vulnerabilities which the ransomware can exploit to enter undetected. Other infiltration methods are malicious third-party ads, compromised pages, illegitimate torrents, fake program updates, etc. However, all of these have one thing in common. They all rely on your carelessness. If you are a little more vigilant and caution, you can prevent an infection which is much easier that dealing with it later. A good anti-malware program can also help you a lot when it comes to keeping your computer infection-free.

Method 1: Restore your encrypted files using ShadowExplorer
Usually, One Ransomware deletes all shadow copies, stored in your computer. Luckily, the ransomware is not always able to delete the shadow copies. So your first try should be restoring the original files from shadow copies.

  1. Download ShadowExplorer from this link:
  2. Install ShadowExplorer
  3. Open ShadowExplorer and select C: drive on the left panel


  4. Choose at least a month ago date from the date field
  5. Navigate to the folder with encrypted files
  6. Right-click on the encrypted file
  7. Select “Export” and choose a destination for the original file

Method 2: Restore your encrypted files by using System Restore

  1. Go to Start –> All programs –> Accessories –> System tools –> System restore
  2. Click “Next

    system restore

  3. Choose a restore point, at least a month ago
  4. Click “Next
  5. Choose Disk C: (should be selected by default)
  6. Click “Next“. Wait for a few minutes and the restore should be done.

Method 3: Restore your files using File Recovery Software
If none of the above method works, you should try to recover encrypted files by using File Recovery Software. Since One Ransomware first makes a copy of the original file, then encrypts it and deletes the original one, you can successfully restore the original, using a File Recovery Software. Here are a few free File Recovery Software programs:

  1. Recuva
  2. Puran File Recovery
  3. Disk Drill
  4. Glary Undelete
