How to remove Zepto virus (Removal Guide)

Zepto virus

Zepto virus is a term used to identify Locky ransomware that encrypts files on the computers it infects and adds a .zepto extension to each file name. The Zepto virus will also leave a .html ransom note named something similar to _6_HELP_instructions in every folder that it encrypts files in.

The .html note contains information about what happened and instructions that explain how to decrpyt your files by obtaining a private key and decryption program. In order to retrieve this you must follow several steps and pay a ransom.

Zepto ransomware is usually spread via malicious browser attachments inside email messages. Here is an example of an email message that is used to spread this ransomware:

Once the malicious attachment is downloaded the ransomware will begin to work in the background. It will scan the computer it infects for file extensions that it can encrypt and provide the computer with an ID that can be used to pay the ransom and decrypt files. Once it encrypts the files it will add a .html ransom note named something similar to _6_HELP_instructions.html in every folder. The ransom note reads:

How to stay protected against future infections

The key to staying protected against future infections is to follow common online guidelines and take advantage of reputable Antivirus and Anti-Malware security software with real-time protection.

Real-time security software

Security software like Malwarebytes and Norton Security have real-time features that can block malicious files before they spread across your computer. These programs bundled together can establish a wall between your computer and cyber criminals.

Common Online Guidelines
  • Backup your computer and personal files to an external drive or online backup service
  • Create a restore point on your computer in case you need to restore your computer to a date before infection
  • Avoid downloading and installing apps, browser extensions, and programs you are not familiar with
  • Avoid downloading and installing apps, browser extensions, and programs from websites you are not familiar with – some websites use their own download manager to bundle additional programs with the initial download
  • If you plan to download and install freeware, open source software, or shareware make sure to be alert when you install the object and read all the instructions presented by the download manager
  • Avoid torrents and P2P clients
  • Do not open email messages from senders you do not know
