Simple_Encoder virus Removal Guide

What is Simple_Encoder ransomware virus?

The way Simple_Encoder ransomware virus works:

Have you received a message on your computer screen, stating that “All your system is encrypted”? If so, there is a great chance that your computer has been attacked by Simple_Encoder virus (also known as Tilde ransomware), which is a powerful malware variant that uses AES encryption algorithm to render victim’s files useless. It is nearly impossible to notice that the computer has been infected with this virus immediately, since it works in the background and encrypts files in deeper system folders, finishing with data that is located in most used folders and Desktop. After encrypting a file, it also adds .~ file extension to it, so for example, a file that is named example.jpg becomes example.jpg.~. Once the damage has been done, Simple_Encoder ransomware scares the victim by launching a message on the computer screen, which includes information about the encryption, price of the ransom that needs to be paid, victim’s ID number and the email address to contact cybercriminals – one1uno243@yandex(.)ru. The virus saves same messages into Desktop and Templates folders under _RECOVER_INSTRUCTIONS.ini name. The virus also changes the desktop image with the img.bmp file, which is stored in TEMP\Simple_Encoder folder.

Simpel_Encoder ransomware note

You should know that ransomware is a very powerful virus, and if you haven’t heard about such viruses before, you should read more about such ransomware variants like Locky, CryptoWall, or CryptXXX virus. The bad thing about these viruses is that without having a decryption key, you cannot decrypt your files anyhow. That is why the developers of such viruses suggest buying it, aka paying the ransom. virus asks to pay 0.8 Bitcoin, which is roughly 523 USD dollars. Now, if you have become a victim of this ransomware, we suggest you to remove Simple_Encoder instead of paying the ransom. Our experience in ransomware research shows that computer security experts often than before succeed to discover working and free decryption tools for particular ransomware viruses. Besides, you should forget the idea of paying the ransom also because if you paid, you would fund cyber criminals and their filthy ransomware projects that they might be developing. To remove Simple_Encoder virus, use an anti-malware software, such as FortectIntego. To recover your files, we suggest waiting. You can also restore all your data in case you have a backup drive. Make sure you remove the ransomware before plugging the drive into your computer!

Distribution of Simple_Encoder virus:

Typically, ransomware viruses are distributed via malicious email campaigns. Frauds typically create safe-looking email accounts, which resemble official email accounts of well-known companies. This strategy helps to deceive inattentive computer users and trick them into opening malicious email attachments quicker. As you have guessed, these malicious emails contain attachments, and they are presented as relevant documents, such as invoices, speeding tickets, bills, CVs, and similar files.

Malware also spreads via so-called drive-by downloads, which means that you can download malicious code into your computer and make it vulnerable to cyber attacks just by visiting an insecure web page. Therefore, we suggest you to protect your computer system with a powerful anti-malware in advance and most importantly, keep all your software up-to-date.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
