How To Remove ABC Ransomware (Virus Removal Guide)

If you cannot open your images, documents, or files and they have a .abc extension, then your computer is infected with the ABC ransomware.

ABC is ransomware that encrypts the personal documents found on the victim’s computer with the “.abc” extension, then displays a message which offers to decrypt the data if payment in Bitcoin is made.

What is the ABC ransomware?

ABC ransomware is a file-encrypting ransomware infection that restricts access to data (documents, images, videos) by encrypting files with the “.abc” extension. It then attempts to extort money from victims by asking for “ransom”, in the form of the Bitcoin cryptocurrency, in exchange for access to data.

The ABC ransomware will scan your computer for images, videos, and important productivity documents and files such as .doc, .docx, .xls, .pdf. When these files are detected, the ransomware will encrypt them and change their extension to “.abc”, so that you are no longer able to be open them.

Once the ABC ransomware has encrypted the files on your computer, it will display a file that contains the ransom note and instructions on how to contact the authors of this ransomware.

This is the ransom note that the ABC ransomware will show to its victims:

All of your files have been encrypted!

The harddisks of your computer have been encrypted with an military grade encryption algorithm.

There is no way to restore your data without a special
software ABC.

To purchase your key and restore your data, please follow these three easy:

1. The price for the software is $300 dollars USD. Payment can be made in Bitcoin only.

2. Bitcoin Address:

3. Once paid, send proof of payment:
Email: recover300dollars@gmail.com
You receive your key in 20 minutes:

To make sure we have the decryptor and it works,
you can send an email: recover300dollars@gmail.com
and decrypt a file for free.
But this file shouldn’t be of any value!

Warning: do not turn off your pc!
If you abort this process, you could destroy all of your data!
Please ensure that your power cable is plugged in!

If your computer is infected with this ransomware, we recommend that you contact the following government fraud and scam sites to report this attack:

In the United States, go to the On Guard Online website.
In Australia, go to the SCAMwatch website.
In Canada, go to the Canadian Anti-Fraud Centre.
In France, go to the Agence nationale de la sécurité des systèmes d’information
In Germany, go to the Bundesamt für Sicherheit in der Informationstechnik website.
In Ireland, go to the An Garda Síochána website.
In New Zealand, go to the Consumer Affairs Scams website.
In the United Kingdom, go to the Action Fraud website.
If your country or region isn’t listed above, we recommend that you contact your country or region’s federal police or communications authority.

Unfortunately, it is not currently possible to decrypt the files encrypted by the ABC ransomware. It may, though, be possible in the future if the decryption keys are recovered from the cybercriminals’ servers. Therefore, if you do not plan on paying the ransom, it is advised that you make an image of the encrypted drives so that you can possibly decrypt them in the future.

How did the ABC ransomware get on my computer?

The ABC ransomware is distributed via spam email containing infected attachments or by exploiting vulnerabilities in the operating system and installed programs.

Here’s how the ABC ransomware might get on your computer:

Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link inside the email). And with that, your computer is infected with the ABC ransomware.
The ABC ransomware was also observed attacking victims by exploiting vulnerabilities in the program installed on the computer or the operating system itself. Commonly exploited software includes the operating system itself, browsers, Microsoft Office, and third-party applications.

Remove the ABC ransomware and recover the files

It’s important to understand that by starting the removal process you risk losing your files, as we cannot guarantee that you will be able to recover them. Your files may be permanently compromised when trying to remove this infection or trying to recover the encrypted documents.

We cannot be held responsible for losing your files or documents during this removal process.
It’s recommended to create a backup image of the encrypted drives before proceeding with the below malware removal instructions.

This malware removal guide may appear overwhelming due to the number of steps and numerous programs that are being used. We have only written it this way to provide clear, detailed, and easy-to-understand instructions that anyone can use to remove malware for free.
Please perform all the steps in the correct order. If you have any questions or doubts at any point, stop and ask for our assistance.

To remove the ABC ransomware, follow these steps:

STEP 1: Start your computer in Safe Mode with Networking
STEP 2: Use Malwarebytes Free to remove the ABC ransomware
STEP 3: Scan and clean your computer with HitmanPro
STEP 4: Double-check for the ABC malware with Emsisoft Emergency Kit
STEP 5: Restore the files encrypted by the ABC ransomware

STEP 1: Start your computer in Safe Mode with Networking

In this first step, we will start your computer in Safe Mode with Networking to prevent ABC malicious drivers and services from loading at Windows start-up. We’re using Safe mode because it starts Windows in a basic state, using a limited set of files and drivers.

Windows 10 or Windows 8Windows 7

Before you enter Safe Mode, you need to enter the Windows Recovery Environment (winRE). To do this, follow the below steps:

Press Windows logo key + I on your keyboard to open Settings. If that doesn’t work, select the Start button, then select Settings.
When the Windows Settings window opens, select Update & Security, then click on Recovery.
Under Advanced startup, select Restart now.

Now that you are in Windows Recovery Environment, you will follow these steps to take you to safe mode:

On the Choose an option screen, select “Troubleshoot“.
On the “Troubleshoot” screen, click the “Advanced Options” button.

On the “Startup Settings” page, click the “Restart”.
After your device restarts, you’ll see a list of options. Select option 5 from the list or press F5 to enter Safe Mode with Networking.
While your computer is running in Safe Mode with Networking, we will need to download, install and run a scan with Malwarebytes (explained in Step 2).

Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.
When the computer starts you will see your computer’s hardware being listed. When you see this information start to press the F8 key repeatedly until you are presented with the Advanced Boot Options.
In the Advanced Boot Options screen, use the arrow keys to highlight Safe Mode with Networking and then press Enter.
While your computer is running in Safe Mode with Networking, we will need to download, install and run a scan with Malwarebytes (explained in Step 2). In some cases, victims may have issues while trying to start the computer in Safe Mode with Networking, if this happens, you can try to scan your computer with Malwarebytes in normal mode.

STEP 2: Use Malwarebytes Free to remove ABC ransomware

While the computer is in Safe Mode with Networking, we will download, install and run a system scan with Malwarebytes.

Malwarebytes Free is one of the most popular and most used anti-malware software for Windows, and for good reasons.

STEP 5: Restore the files encrypted by the ABC ransomware

Unfortunately, it’s not possible to recover the files encrypted by the ABC ransomware because the private key which is needed to unlock the encrypted files is only available through the ecybercriminals. However, below we’ve listed three methods you can use to try and recover your files.

Make sure you remove the malware from your computer first, otherwise, it will repeatedly lock your system or encrypt files. If you suspect that your computer is still infected with malware, you can run a free scan with ESET Online Scanner.

Method 1: Search for a ABC ransomware decryption tool

At the time of writing this article, there was no decryption tool available for the ABC ransomware. However, the cybersecurity community is constantly working to create ransomware decryption tools, so you can try to search these sites for updates:

Method 2: Try to recover your files with Recuva Free

With this second option, we will install and try to recover the encrypted files with Recuva, a free data recovery tool.

Download Recuva Free.

You can download Recuva from the below link.
