If you are seeing a “Atención! Su navegador ha sido bloqueado” notification within Internet Explorer, Firefox, Safari or Chrome, then you have redirected to a web page that contains a malicious javascript code. The “Atención! Su navegador ha sido bloqueado” message is basically just a web page containing a malicious javascript that does not allow you to close the browser window or switch to a different web page.

The “Atención! Su navegador ha sido bloqueado” virus will display a bogus notification that pretends to be from Policía and Grupo de Delitos Telemáticos (Spanish Police) and states that your computer has been blocked due to it being involved with the distribution of pornographic material, spam and copyrighted content.
It goes on to say that you need to pay a ransom of 100 Euro in order to get access to your files and computer again. In order to pay this ransom you need purchase a Ukash or Paysafecard voucher and submit it in the web browser. The malware’s authors prefer these payment services because transactions made through them cannot be reversed and are hard to trace.

If your computer is infected with the “Atención! Su navegador ha sido bloqueado” browser hijacker, this infection will display a localized webpage that covers the entire web browser of the infected computer and demands payment for the supposed possession of illicit material. The message displayed by this ransomware infection can be localized depending on the user’s location, with text written in the appropriate language.
The text of the “Atención! Su navegador ha sido bloqueado” web page is:

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. Use a good antivirus and keep it up-to-date.

    Shield Guide

    It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

  2. Keep software and operating systems up-to-date.

    updates-guide

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    Trojan Horse

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    warning sign

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.

    backup sign

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Choose strong passwords.

    lock sign

    Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

  9. Be careful where you click.

    cursor sign

    Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

  10. Don't use pirated software.

    Shady Guide

    Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
