What is SavingsCool?

The Malwarebytes research team has determined that SavingsCool is a browser hijacker. These so-called "hijackers" manipulate your browser(s), for example to change your startpage or searchscopes, so that the affected browser visits their site or one of their choice. This one also displays advertisements.

  • 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.

Is there anything else I need to do to get rid of SavingsCool?

  • You may be prompted for a second reboot, which is needed to remove the proxy settings.
How would the full version of Malwarebytes Anti-Malware help protect me?
