What is Fast Computer?
The Malwarebytes research team has determined that Fast Computer is a "system optimizer". These so-called "system optimizers" use intentional false positives to convince users that their systems have problems. Then they try to sell you their software, claiming it will remove these problems.
More information can be found on our Malwarebytes Labs blog.
How do I know if I am infected with Fast Computer?
This is how the main screen of the system optimizer looks:

You will find these icons in your taskbar, your startmenu, and on your desktop:

and see these warnings during install:


and these types of screens during "operations":

How did Fast Computer get on my computer?
These so-called system optimizers use different methods of getting installed. This particular one was downloaded from their website:

How do I remove Fast Computer?
Our program Malwarebytes can detect and remove this potentially unwanted application.
- Please download Malwarebytes for Windows to your desktop.
- Double-click MBSetup.exe and follow the prompts to install the program.
- When your Malwarebytes for Windows installation completes, the program opens to the Welcome to Malwarebytes screen.
- Click on the Get started button.
- Click Scan to start a Threat Scan.
- When the scan is finished click Quarantine to remove the found threats.
- Reboot the system if prompted to complete the removal process.
- No, Malwarebytes removes Fast Computer completely.
We hope our application and this guide have helped you eradicate this system optimizer.
As you can see below the full version of Malwarebytes would have protected you against the Fast Computer installer. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
and both Malwarebytes Premium and Browser Guard block access to their domain:
