What is CPUID CPU-Z?

The Malwarebytes research team has determined that CPUID CPU-Z is a trojan.
This particular one injects downloaded JavaScript (JS) files into browser sessions and sets a proxy accompanied with a false SSL certificate to perform a man-in-the-middle (MITM) attack.

How do I know if my computer is affected by CPUID CPU-Z?

You may see this entry in your list of installed software:

and this icon in your startmenu and on your desktop:

How did CPUID CPU-Z get on my computer?

Trojans use different methods for distributing themselves. This particular one was bundled with other software.

How do I remove CPUID CPU-Z?

Our program Malwarebytes can detect and remove this malware.
  • Please download Malwarebytes to your desktop.
  • Double-click mb3-setup-consumer-{version}.exe and follow the prompts to install the program.
  • Then click Finish.
  • Once the program has fully updated, select Scan Now on the Dashboard. Or select the Threat Scan from the Scan menu.
  • If another update of the definitions is available, it will be implemented before the rest of the scanning procedure.
  • When the scan is complete, make sure that all Threats are selected, and click Remove Selected.
  • Restart your computer when prompted to do so.
Is there anything else I need to do to get rid of CPUID CPU-Z?
  • No, Malwarebytes removes CPUID CPU-Z completely.
How would the full version of Malwarebytes help protect me?

We hope our application and this guide have helped you eradicate this hijacker.

As you can see below the full version of Malwarebytes would have protected you against the CPUID CPU-Z hijacker. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.

and it blocks the domains where the trojn was downloaded from by the bundler:

and even if you should get infected it blocks the exploit that the trojan uses to perform the man-in-the-middle attack:
