The customer's web browser is likely infected by a browser hijacker, which is a type of malware that changes the browser's settings and redirects the user to malicious websites. A browser hijacker can also steal the user's personal data, display unwanted ads, and install more malware on the device. To remove a browser hijacker, the user should first uninstall the browser from the Control Panel, then scanthe device with an antivirus or anti-malware program, and finally install a trusted browser from a legitimate source. Deleting the browser cookies and history, resetting the browser settings, or changing the browser default search engine may not be enough to get rid of the browser hijacker, as it may have embedded itself into the system or other browser components.
