What is Dinosecurity.exe?

The Dinosecurity.exe process is part of a Trojan Horse that uses the infected computer’s resources to mine for digital currency without user permission. This Trojan Miner uses the Dinosecurity.exe process name to disguise itself as a legitimate process.

When this malicious program is installed, the Dinosecurity.exe process will use more than 80% of your CPU’s power and graphics card’s power. What this means, is that when the miners are running you will find that your computer is running slower and games are stuttering or freezing because the Dinosecurity.exe Miner is using your computer’s resources to generate revenue for themselves. This will cause your CPU to run at very hot temperatures for extended periods of time, which could shorten the life of the CPU.

Unfortunately, most victims will not realize that they are infected with this Trojan unless they look in Task Manager and notice an Dinosecurity.exe program utilizing over 80% of the CPU on the computer.

When infected with the Dinosecurity.exe CPU Miner Trojan, other common symptoms include:

  • Very high CPU and graphics cards usage
  • Dinosecurity.exe and other suspicious processes will run in the background.
  • Windows minimize and maximize slowly, and programs run slower.
  • Programs don’t launch as quickly.
  • General slowness when using the PC.

How did Dinosecurity.exe get on my computer?

Dinosecurity.exe Trojan is installed by the users, whether that is knowingly or not. Often, this type of program is offered through advertisements or bundled with other programs, leaving the user puzzled about where this software came from.

You should always pay attention when installing software because often, a software installer includes optional installs. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.

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.
