Introduction
There are plenty of browser hijackers that will redirect the users’ search queries to cse.google.com. This is most likely done to generate advertising revenue by using Google Custom Search for its search results. These unwanted Google Custom Search redirects are caused by browser hijackers that are installed by the users, whether that is knowingly or not. Often, this type of program is offered through advertisements or bundled with other software, leaving the user puzzled where this software came from. Browser hijackers are a type of malware created to modify Internet browser settings without the user’s knowledge or consent. 
Symptoms
When the Google Custom Search browser hijacker is installed on a PC, common symptoms include:
- Changing the web browser’s default homepage to Google Custom Search
- Changing the browser’s search provider, a built-in search box to Google Custom Search
- Ability to modify the ‘new tab’ functionality to launch the modified search portal page
- Loads into the web browser via an extension or add-on
- Web Browser shortcuts are hijacked to redirect to Google Custom Search
How to remove Google Custom Search redirect (Virus Removal Guide)
- Identify the malicious program and uninstall it: This is a manual step. You can look into the list of programs installed in the ‘apps and features’ section in settings and uninstall any suspicious program.
- Use an antivirus tool: It is unlikely that Windows defender will pick up this as Google Custom Search in itself is not malicious. It is advised to use dedicated software like Malwarebytes or Hitman Pro to scan and remove any viruses.
- Reset browser settings to default: If you are using chrome, you will find this at settings->advanced->reset.
