Why Does My Search Engine Keep Changing to Search Marquis

If you’ve ever noticed that your search engine keeps changing to “Search Marquis,” you’re not alone. Many internet users have encountered this frustrating issue, where their preferred search engine settings get altered without their consent. In this article, we will explore the reasons behind this phenomenon and discuss effective solutions to regain control over your search engine preferences.

Understanding Search Engine Defaults

By default, web browsers have predefined search engine settings, and they usually come with a popular search engine like Google or Bing. When installing a new browser, settings are set to the default search engine. However, some users prefer using different search engines that suit their specific needs and preferences.

The Influence of Installed Software

Software installations may lead to search engine changes. Additional software bundled with programs can modify browser settings during installation, often mentioned in terms and conditions, but often overlooked by users.

Browser Extensions and Add-ons

Extensions can enhance browsing but cause unwanted search engine changes. Some extensions may include features that automatically modify your search engine settings without your knowledge.

Search Engine Hijacking and Malware

Search engine hijacking maliciously redirects searches to specific engines like “Search Marquis.” This can be a result of malware or potentially unwanted programs (PUPs) that take control of your browser’s settings.

Clearing Browser Cache and Cookies

Sometimes, cached data or cookies within your browser can cause unexpected changes to your search engine. Clearing these temporary files might resolve the issue and bring back your preferred search engine.

Updating Your Browser

Outdated browsers may be vulnerable to software exploitation and setting modifications. Ensuring that your browser is up to date reduces the risk of search engine changes caused by security breaches.

Managing Search Engine Settings

Most browsers allow users to customize their search engine preferences. Understanding how to manage and set your desired search engine as the default can help prevent unwanted changes.

Antivirus and Malware Scans

Running regular antivirus and malware scans can detect and eliminate any harmful software that may be affecting your browser’s behavior.

Checking for Unwanted Programs

Performing a system check for unwanted programs can help you identify and remove any applications responsible for changing your search engine settings.

Avoiding Clicking on Suspicious Links

Clicking on suspicious links or visiting unsafe websites can lead to unwanted software installations, potentially leading to search engine changes.

Educating About Safe Browsing Practices

Educating about safe browsing reduces search engine risks.

Utilizing Secure Websites

Prioritize using secure websites with HTTPS encryption to safeguard your browser from potential threats.

Regular Software Updates

Updating all your software, including browsers and applications, helps ensure you have the latest security patches to protect against search engine hijacking attempts.


Encountering sudden changes in your search engine can be frustrating and intrusive. Understanding the reasons empowers control and prevents disruptions. By staying vigilant, keeping your software updated, and adopting safe browsing habits, you can maintain your preferred search engine without interference from unwanted software.
