When you install Panda Free Antivirus 18.0 and if you won’t pay attention during its installation, along with the antivirus, Panda Safe Web will also be installed on your computer and it will be set as default search engine and default home page in browsers. As a result, the Panda Safe Web extension will be added to browsers like Chrome, Internet Explorer and Firefox (as a toolbar) and Vivaldi browsers.

When you launch Chrome, or Internet Explorer, the browser prompts you to enable the Safe Web extension. Though the extension provides benefits to users in a web browser by showing safety ratings for websites you visit and offers phishing protection, but it changes browser search settings to pandasecurity.mystart.com (powered by Yahoo).
