Aleta virus Removal Guide
What is Aleta ransomware virus?
Aleta ransomware – a computer virus that follows BTCWare's example
Aleta is a crypto-virus that locks files with a combination of AES and RSA encryption keys.
Aleta is a ransomware-type cyber threat that uses AES and RSA encryption algorithms to make files on the affected Windows computers. Malware also appends .[email].aleta file extension to the targeted files and delivers ransom-demanding instructions in !#_READ_ME_#!.inf file. However, it's not a unique virus. It is just a new version of BTCWare ransomware. For this reason, it is also known as “BTCWare Aleta ransomware.”
|Most affected countries||Argentina, Belgium, and Spain|
|Cryptography||A combination of AES and RSA|
|Appended file extensions||.[email@example.com].aleta
|Symptoms||Encrypted files, system slowdowns, Windows errors, unresponsive programs|
|Decryption||Might be possible with BTCWare decryptor|
|To uninstall Aleta, install ReimageIntego and run a full system scan|
Aleta virus enters the system as a Trojan. On the affected computer, it makes various changes, installs necessary components and starts data encryption procedure. During the encryption, the crypto-virus appends .aleta file extension. Additionally, crooks include one of the following email address in the added suffix:
Aleta ransomware asks to contact cyber criminals in order to recover missing files.
According to the ransom note, delivered soon after file encryption, victims have to send an email to one of the provided emails in order to recover encrypted files. Authors of Aleta ransomware provide a detailed guide in the !#_READ_ME_#!.inf:
All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail firstname.lastname@example.org in body of your message write your ID
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files.
Free decryption as guarantee
Before paying you can send us up to 1 file for free decryption. The total size of files must be less than 1Mb (non archived), and files should not contain valuable information. (databases, backups, large excel sheets, etc.)
How to obtain Bitcoins
The easiest way to buy bitcoins is LocalBitcoins site. You have to register, click 'Buy bitcoins', and select the seller by payment method and price.
Also you can find other places to buy Bitcoins and beginners guide here:
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.
Your ID –
Attackers use psychological terror and threaten victims to contact them immediately. The sum for the Aleta decryptor is said to be set due to the speed of how fast people send the email to crooks. According to victims’ reports, authors of this ransomware suggest decrypting encoded files for 2 Bitcoins which is an enormous sum of money.
Aleta virus delivers a ransom note in a text file as soon as data encryption is over.
The attackers suggest that the victim has an opportunity to test the BTCWare Aleta decrypter by sending three small files to criminals via email, no larger than 1Mb in size. The criminals promise to send back decrypted versions of the files to prove that they actually can decrypt their files.
However, we do not recommend contacting creators of Aleta virus. These dishonest people created this malicious program in order to collect money illegally. So, they cannot be trusted. Once they receive your payment, they might leave you with those two or three decrypted files. They may not provide you a working decryption tool. Thus, paying the ransom might increase your loss.
Aleta malware demands to pay the ransom in Bitcoins. However, the size of the payment differs from victim to victim.
Instead of thinking about data recovery, you should think about virus elimination. Malware makes the system vulnerable and unstable. So, you will not be able to use your PC safely and properly. In order to remove Aleta completely, you have to use a decent anti-malware software such as ReimageIntego. Trying to delete a ransomware-type virus often results in failure due to lack of computing skills, so if you are an inexperienced PC user, you shouldn’t try to eliminate the virus manually.
You can find informative guidelines on how to restore your data right below the article. In case you are looking for Aleta removal instructions in a different language, such as Polish or German, check out websites like UsunWirusa or DieViren.
Aleta virus is a version of BTCWare ransomware. Just like previous BTCWare versions, it marks encrypted files by appending [email].aleta file extensions to them.
Ways used for spreading ransomware virus
The described virus typically infiltrates the target system using RDP attacks. Cyber criminals seek to compromise admin accounts that have the right to control organization network remotely, and if they succeed to infect them, they can easily take over the target system and infect all devices with ransomware.
Keep in mind that even the strongest anti-malware programs become useless if you use weak admin passwords. In such case, crooks can brute force these passwords in a day and then fully control the target computer remotely.
There are many ways to fight ransomware; however, the general rules to protect you against ransomware attacks are:
- Install and keep an anti-malware program up-to-date.
- Create data backups regularly. You can find a guide on how to backup your data here.
- Never use weak passwords on your accounts, especially on remote system access software.
- Do not click on vague links while browsing the web and do not open emails sent by unknown people.

There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
