Aleta ransomware removal instructions
What is Aleta?
Aleta is an updated version of a ransomware-type virus called BTCWare. Once infiltrated, Aleta encrypts data and appends the "[developers'_email].aleta" extension to the name of each encrypted file (for example, "sample.jpg" might be renamed to a filename such as "sample.jpg.[firstname.lastname@example.org].aleta"). To see the full list of email addresses used within these extensions, click here. Following successful encryption, Aleta creates an HTA file ("!#_READ_ME_#!.hta") and places it in each folder containing encrypted files.
The HTA file contains a message informing victims of the encryption. To restore files, victims are encouraged to contact cyber criminals and pay a ransom. It is currently unknown whether Aleta uses symmetric or asymmetric cryptography, however, in either case, decryption requires a unique key. Criminals store this key on a remote server and make ransom demands for its release. The cost is unconfirmed and apparently depends on how swiftly the victim contacts Aleta's developers. Most ransomware developers demand the equivalent of between $500 and 1500 in Bitcoins. Never trust these people. Research shows that cyber criminals often ignore victims once ransoms are paid. Paying does not guarantee that your files will ever be decrypted and there is a high probability that you will be scammed. Never attempt to contact these people or pay any ransom. Unfortunately, there are no tools capable of restoring files encrypted by Aleta. Therefore, you can only restore your files/system from a backup.

Aleta shares many similarities with Blocking, ONYONLOCK, YourRansom, RSAUtil, and dozens of other ransomware viruses. As with Aleta, these malware infections also encrypt files and make ransom demands. The only major differences are type of encryption algorithm used and size of ransom. Be aware, however, that most ransomware employs algorithms that generate unique decryption keys (for example, RSA, AES, etc.) and, therefore, unless the malware is bug-ridden, restoring files manually (without developer assistance, which is not recommended) is mostly impossible.

How to protect yourself from ransomware infections?
To prevent ransomware infections, be very cautious when browsing the Internet. Never open files received from suspicious/unrecognizable emails or download software from unofficial sources. Keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite.

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 Aleta 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 Aleta 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 Aleta 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 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 Aleta 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.
