1. Understanding the Reasons Behind Yahoo Redirects

The persistent redirection of your browser to Yahoo can stem from several underlying causes. Identifying the correct reason is crucial for implementing the appropriate solution.

1.1 Browser Hijackers: The Malware Culprit

One of the primary reasons your browser keeps defaulting to Yahoo is the presence of browser hijackers. These are malicious software programs designed to alter your browser settings without your consent, redirecting your searches and web traffic to specific sites, often for advertising revenue or to gather data.
