What feature might a browser include to help protect against spyware?

Ad-blocking capabilities are a crucial feature in many modern web browsers designed to protect users against spyware and other forms of unwanted software. Spyware is typically delivered through deceptive advertisements, pop-ups, or questionable websites that trick users into clicking on malicious links. By including ad-blocking capabilities, a browser can prevent these ads from appearing in the first place, thus significantly reducing the risk of accidental clicks on harmful content.

This feature helps to create a safer browsing environment by filtering out known sources of spyware and other intrusive ads, allowing users to navigate the web more securely. Without these protections, users are more vulnerable to malicious downloads and phishing attacks that could compromise their personal information and system security.

The other options—such as increased bandwidth, the ability to customize themes, and automatic page translation—do not directly contribute to spyware prevention and enhance the browsing experience in different, unrelated ways.
