Anti-fraud tools are security features that look for signs of scams in messages, websites, or payment activity. Depending on the product, they may block a risky page, warn that a message or link looks suspicious, or flag a transaction for review. They are distinct from antivirus functions, which primarily detect or stop malicious software.
These tools matter because fraud often relies on tricking people rather than exploiting a device. In real attacks, criminals may use phishing messages, fake payment pages, or impersonation to steal credentials or money. A security suite can help identify some warning signs, but coverage varies: a feature may only issue an alert, and its protection may depend on the browser, email service, or payment workflow. Users should check what a tool actually detects and continue verifying unexpected requests independently.
