What is SPC Optimizer?

The Malwarebytes research team has determined that SPC Optimizer is a fake system optimizer. These so-called "registry cleaners" 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 Unpacked blog.

How do I know if I am infected with SPC Optimizer?

This is how the main screen of the system optimizer looks:

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

and this task in your Task Scheduler:

How did SPC Optimizer 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 SPC Optimizer?

Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted application.
  • Please download Malwarebytes Anti-Malware to your desktop.
  • Double-click mbam-setup-{version}.exe and follow the prompts to install the program.
  • At the end, be sure a check-mark is placed next to:
    Launch Malwarebytes Anti-Malware
  • Then click Finish.
  • Once the program has loaded, select Scan Now. Or select the Threat Scan from the Scan menu.
  • If an update 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 SPC Optimizer?
  • No, Malwarebytes' Anti-Malware removes SPC Optimizer completely.
  • This PUP creates a scheduled task. You can read here how to check for and, if necessary, remove Scheduled Tasks.
How would the full version of Malwarebytes Anti-Malware help protect me?

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

As you can see below the full version of Malwarebytes Anti-Malware would have protected you against the SPC Optimizer installer. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
