What is ScanUtilities?
The Malwarebytes research team has determined that ScanUtilities 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 remove ScanUtilities?
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 ScanUtilities 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 ScanUtilities installer. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
