The correct answer is A. Man-in-the-browser. The symptoms described - browser slowness, crashes, frozen hourglass, new search toolbar, and increased memory - are classic indicators of a Man-in-the-browser (MitB) attack, which injects malicious code directly into the browser process.

Why each option
The symptoms described - browser slowness, crashes, frozen hourglass, new search toolbar, and increased memory - are classic indicators of a Man-in-the-browser (MitB) attack, which injects malicious code directly into the browser process.
Man-in-the-browser malware operates by injecting itself into the browser process, hooking browser APIs to manipulate web sessions in real time. This injection causes excessive memory consumption, browser instability (crashes and slowness), and can install unauthorized toolbars or redirect search engines. The hourglass being stuck reflects the browser's CPU/memory being consumed by the malicious injected code.
A Spoofer is a technique used to falsify the origin of network traffic or communications (e.g., IP or DNS spoofing) and does not manifest as browser performance degradation or unauthorized toolbar installation.
Spyware silently collects user data and transmits it to a third party without the user's knowledge, but it does not typically cause visible browser crashes, toolbar injections, or the hourglass freezing symptom described.
Adware primarily generates unwanted advertisements and may slow a system over time, but it does not typically cause frequent browser crashes, a stuck hourglass, or the level of memory consumption described in this scenario.
