The extension .nacro is associated with a ransomware infection called STOP. STOP Nacro virus is a data locker ransomware that infects computer systems with the goal to encrypt personal files and demand a ransom fee for their recovery. Since it uses a strong cipher algorithm to corrupt target files, it leaves all .nacro files inaccessible. When the attack ends, Nacro ransomware virus drops a ransom message file and loads it on the screen to extort a ransom payment. The file could be found on the desktop as well as in folders that contain encoded .nacro files.
For the sake of your security, we recommend that you avoid any negotiations with cybercriminals and navigate to our Nacro Virus removal guide. It presents information on how to get rid of malicious files, secure your PC and attempt to restore .nacro files with alternative data recovery approaches.

Distribution of Nacro Virus
Nacro virus is a new data locker ransomware that has been released in active attack campaigns against computer users worldwide. The threat could be utilizing common tactics of distribution to infect computer systems.
One of the easiest ways for the criminals to spread the payload of Nacro ransomware is by attaching it to email messages that are later released in active attack campaigns. The method allows hackers to send the virus to large lists of potential victims. The attachments to malicious email spam messages usually have Word documents or other types of files which users open without hesitation. Once opened on a target host these compromised files trigger the ransomware payload and infect the device with Nacro crypto virus. Another infection tactic related to emails is hyperlink inserted in the content of the messages. The links are usually labeled as leading to a familiar website or a file of user interest.
Computer criminals behind this new ransomware can be using malicious sites or download portals to distribute malware of different kinds, including Nacro virus. A popular option is the use of infected documents which may be of different types ‒ spreadsheets, rich text documents, presentations and databases. They are modified to initiate the virus once the built-in scripts are run. Usually when the files are opened a notification will ask the users to run the macros (scripts). If this is done the infection follows.
The hacker-controlled sites are specialist portals that have been created either manually or automatically by the criminals behind Nacro virus. They can either directly distribute the threat by initiating various scripts or automated operations or link to such instances. Redirects are usually caused by email interaction, ad networks or other browsing activity. However one of the main sources is the availability of browser hijackers. They are malicious add-ons made for the most popular web browsers ‒ Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Microsoft Edge and Safari. Once installed they not only infect the users with the malware but also redirect the victims to a hacker-controlled site. Depending on the configuration the browser hijackers can also steal sensitive information such as any stored passwords, account credentials, history, bookmarks, form data and settings.
Impact of Nacro Virus
The so-called Nacro Virus has been detected in active attack campaigns. It is based on the code of the infamous ransomware family STOP. The code of this threat is designed to plague essential system settings with the purpose to reach target types of files and encode them with sophisticated cipher algorithm.
The beginning of the attack is marked by the execution of Nacropayload file. Soon after the occurrence of this event, the threat becomes able to pass through several attack stages. At first, it triggers the creation of additional malicious files that support all following operations. The ransomware could either create or drop them on the system. Typically, threats like Nacro Virus are designed to place malicious files in system folders like %Roaming% , %Windows% , %AppData% , %Local% , %Temp%
Once Nacro Virus establishes the files, it starts executing them in a predefined order. As a result, it affects some essential system settings. Affected could be some main registry keys stored by the Registry Editor, legitimate processes and other major components that control the regular system performance.
Following system corruption, Nacro ransomware utilizes a built-in encryption module to complete its main purpose – data encryption. Since this module is designed to transform the code of targeted files with a sophisticated cipher algorithm, the files remain unusable until their code is reverted back to its original state.
All files that are renamed with the extension .nacro are encrypted by the ransomware. Unfortunately, they could be all files that store valuable data of your like:
- Documents
- Archives
- Backups
- Databases
- Images
- Videos
- Music
Following data corruption, Nacro STOP drops a text file which contains its ransom message. This file may automatically be loaded on the screen as its purpose is to blackmail you into paying hackers a ransom fee
Have in mind that even a successful ransom payment does not guarantee the recovery of .nacro files. Hackers could trick you once again by neglecting your messages or sending you a broken decryption tool.
Remove Nacro Ransomware Virus and Restore PC
Please note that paying the requested ransom fee to cybercriminals does not really solve your problem with Nacro crypto virus. In fact, you only encourage hackers to continue spreading ransomware of this kind. Instead, you must remove the threat immediately, and only then look for optional ways to recover your data.
WARNING! Manual removal of Nacro ransomware virus requires being familiar with system files and registries. Removing important data accidentally can lead to permanent system damage. If you don’t feel comfortable with manual instructions, download a powerful anti-malware tool that will scan your system for malware and clean it safely for you.
