Vortex ransomware removal instructions
What is Vortex?
Vortex is a ransomware-type virus developed using AESxWin - an open-source file encryption project. This malware is virtually identical to the Polski and Flotera viruses. Following successful infiltration, Vortex encrypts various files using AES-256 cryptography and appends the ".aes" extension to the name of each encrypted file. For example, a file such as "sample.jpg" might be renamed to "sample.jpg.aes". Once the files are encrypted, Vortex creates a text file ("ODZSZYFRUJ-DANE.txt"), placing it on the desktop.
The text file contains a ransom-demand message in Polish stating that files are encrypted and the only way to restore them is to purchase a unique decryption key. As mentioned above, Vortex employs AES cryptography and, thus, claims that files cannot be restored without a key are unfortunately accurate. Cyber criminals (developers of Vortex ransomware) store this key on a remote server and generate revenue by blackmailing victims to receive it. The size of ransom is $199. To submit payment, victims are encouraged to contact criminals via email addresses ("email@example.com" or "firstname.lastname@example.org") provided, and to follow the instructions. Victims are also permitted to attach two selected files, which are then decrypted and returned - presumably as proof that decryption is possible. Despite these demands and threats, never trust these people. Cyber criminals often ignore victims, once payments are submitted. You should never attempt to contact these people or pay any ransom - you will support their malicious businesses. Furthermore, there is a high probability that you will be scammed. There are currently no tools capable of cracking AES cryptography and restoring files encrypted by Vortex. The only solution to this problem is to restore files/system from a backup.

There are dozens of ransomware-type viruses similar to Vortex. The list of examples includes CryptoDevil, Karmen, Matrix, FileLocker, and Enjey Crypter. As with Vortex, these viruses also encrypt files and make ransom demands. The only noticeable differences are type of encryption algorithm (symmetric/asymmetric) used and cost of decryption key. Cyber criminals often proliferate ransomware-type viruses by employing trojans, fake software updaters, spam emails (infectious attachments, and third party software download sources (freeware download and free file hosting websites, torrents, etc.) Therefore, use a legitimate anti-virus/anti-spyware suite and keep installed applications up-to-date. Bear in mind, however, that criminals often use fake updaters to proliferate malware, so never update software via third party tools. Furthermore, be cautious when opening files received from suspicious emails, and when downloading software from unofficial sources.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Vortex ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Vortex ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Vortex are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To regain control of the files encrypted by Vortex, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Vortex ransomware.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
