This removal guide shows detailed information about Alka virus as well as illustrated instructions on how to remove this ransomware from the infected PC. You will also be presented with several alternative data recovery methods.
Alka Virus Removal
According to the information shared by the security researcher Michael Gillespie, the founder of Alka virus, the threat is the latest strain of a vicious ransomware family dubbed STOP/Djvu. Like its predecessors, Alka is designed to corrupt computer operating systems with the goal to pass through several attack stages. During the attack, the ransomware encrypts files and appends the .alka extension to their filenames. The primary goal of Alka is to force you to contact hackers at helpmanager@firemail.cc or helpmanager@iran.ir so that they can send you back their demands. Typically, what they ask for is a ransom fee for a decryption tool and a unique key. The amount of the ransom varies from $490 to $980 in Bitcoin.
Unfortunately, most data locker ransomware like Alka lock files with strong cipher algorithms that can be decrypted by specific tools only. However, we don’t recommend that you pay hackers the ransom as there is a real chance that you will get scammed once again. Lots of times victims who pay the ransom don’t receive the key or the decrypter. The best way to recover .alka files is from a previously created backup.

What is Alka Ransomware?
Alka is a ransomware infection that has recently been spotted in the wild. As a strain of one of the most vicious ransomware families – STOP, the threat disrupts system security and encodes personal files. In the beginning, the ransomware corrupts system settings that help it to evade detection and hide malicious files. Beware that when an infection with Alka ransomware occurs, some major registry keys in the Registry Editor are contaminated. The reason is that their functionalities can enable it to launch malicious files every time the infected system is started.
As for the spread of Alks, techniques like spam emails, email attachments, hacked web pages, and corrupted freeware installers are likely to be utilized. Since malspam propagation technique enables hackers to spread their malicious code on a large scale it is considered to be the main one. Malwpam or massive email spam campaigns that try to deliver malicious code has its traits.
So how to recognize an email that endangers the overall security of your PC and data stored on its drives? First: Does the email have an attached file of common type or a link presented as a button, an image, a plain URL or another clickable form? If the answer is positive then avoid interacting with these elements. If you believe that you should view the content then scan the file / link with online malware scanners like VirusTotal. The results will provide information about the security level of the content.
Among the most popular Windows file types that are used by malware are executable files, documents and other Microsoft Office files, application files, script files, PDFs, temporary files and other.
.Alka File Extension
All initial malicious changes performed by the ransomware aim to enable it to reach the data encryption stage. During this stage, the ransomware launches a strong cipher algorithm to encrypt personal files. All drives and folders are scanned for commonly used types of files as they are likely to store valuable user data. As a result of encryption, corrupted files receive the malicious extension .alka .
Unfortunately, encrypted files remain inaccessible after encryption. The malicious file extension .alka may appear at the end of document, music, project, database, image, video, backup, archive, and audio files. It should be noted that in order to remain unnoticed Alka displays a fake Windows update pop-up during the encryption:
At the end of the attack, Alka virus drops a ransom message to extort a ransom fee from victims. In fact, the primary goal of Alka virus is to blackmail you into paying a ransom fee to hackers. So its ransom note called _readme.txt informs that the decryption of corrupted files can be realized after you pay hackers a ransom fee ($490 – $980 in Bitcoin). Here is the full text content of this file:

How to Remove Alka Virus
The so-called Alka ransomware virus is a threat with a highly complex code that disrupts system security in order to encrypt personal files. Hence the infected system could be used in a secure manner again only after you remove all malicious files and objects created by the ransomware. The steps presented in the ransomware removal guide below will help you with the complete removal process. Beware that the manual ransomware removal is suitable for more experienced computer users. If you don’t feel comfortable with the manual steps navigate to the automatic part of the guide. It is also worth mentioning that personal data remains encrypted even after the complete removal of Alka virus. Its removal only prevents it from causing further encryptions and security issues.
Step 5 from our Alka ransomware removal guide presents alternative data recovery methods that may be efficient for the recovery of encrypted files. Beware that you should make copies of all encrypted files and save them on a flash drive for example before the beginning of the recovery process.

Step 2: Uninstall Alka and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Alka on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Alka there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Alka
Step 5: Try to Restore Files Encrypted by Alka.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
