This article is created with instructions to aid you to remove CryptoMix ransomware and try to restore .lesli encrypted files.
A ransomware virus, believed to be part of the CryptoMix malware family is believed to cause some infections and encrypt the files of the infected computers, asking ransom money in a text, named “INSTRUCTION RESTORE FILE.TXT”. In those instructions, the approximate sum of 0.5 to 1.5 BTC may be requested from the victims to pay to get a decryptor for the encoded files. In case you have become a victim of the .lesli virus, we advise you not to perform any payment or communication with the cyber-criminals and instead to focus on removing the malware and encrypting files encoded by this malware by yourself.

Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.
How .lesli CryptoMix Ransomware Infects
For it to cause a successful infection, the criminals behind CryptoMix .lesli threat might perform several different actions. One of those is to obfuscate a malicious code or file and disguise it as a legitimate file for the file to fool an inexperienced user into opening it. This is achievable via the usage of socially engineered phishing e-mails containing fraudulent information, like the victim’s need to check his bank account balance sheet, for example. Opening the attachment results in the activating of a malicious script without Windows Firewall or any other defensive software detecting it (in most cases). After this is done, the virus begins to drop malicious files with different names in several Windows folders that contain different names:
As soon as the malicious files are dropped on your computer by the .lesli Infection module, the malware may begin to encrypt files of the following file types:
After the encryption process has been completed, the virus may add a file extension that contains an e-mail address and the .lesli suffix. Files encrypted by .lesli may appear like the following:
As soon as this has been completed, the .lesli virus may drop a .txt file, named “INSTRUCTION RESTORE FILE.TXT” that aims to notify the user of the situation and provide instructions on decrypting the files by paying a hefty ransom fee, which is highly inadvisable by malware researchers.
The .lesli Virus – Remove it and Try to Get the Files Back
To fully remove the ransomware from your computer, malware researchers strongly advise users to focus on using an advanced software for malware removal that will automatically take care of the threat. For this and more removal instructions, you may want to refer to the removal instructions below.

4. Try to Restore files encrypted by .lesli CryptoMix
Try to Restore Files Encrypted by .lesli CryptoMix
Ransomware infections and .lesli CryptoMix aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
