Why Does My Default Search Engine Keep Changing to Yahoo | Reasons & Fixes

The question “Why does my default search engine keep changing to Yahoo?” is asked across forums everywhere now and then. Numerous users found their search engine maliciously modified into Yahoo and others, especially for Google Chrome users, which implies that you may encounter Browser hijacking. Rest assured, this can result from several reasons; simply check and figure out how to solve it.

This could be the most possible reason, especially when you have McAfee installed on your device. Some legitimate antivirus provides safe-search features that are intended to protect your browser engine, so it keeps changing your preferred search engine to the one it thinks “secure”. Yet, it leads to an annoying result. For instance, McAfee’s WebAdvisor and Secure Search extension is still complained about for changing Chrome into Yahoo. Even after manually reverting to Chrome, the search engine still gets modified. So, this can answer “Why does my Google Chrome keep changing to Yahoo?”

Attention please, you may have mistakenly downloaded malware or virus applications/extensions. This kind of malware can disguise itself as a clean and harmless app/extension, intrude on your system, and hijack your browsers to a malicious site, sometimes with tons of ads.

Some free apps will promote some other related apps/sponsored apps with pre-checked boxes during installation; if you don’t manually uncheck them, extra apps will be installed as well, which are called PUAs, i.e., Potentially Unwanted Apps. Then, they will sneakily modify your web settings, including browser search engines.
