Which symptom is commonly observed when a Web browser’s homepage changes automatically due to malware?

• A. The Web browser's homepage changes automatically.
• B. The browser never changes homepages.
• C. The browser runs faster than normal.
• D. The browser cannot access any websites.

Answer: (A)

When malware affects a browser, a common sign is that the homepage changes automatically. This happens because a browser hijacker modifies the browser’s startup settings so it loads a different page every time you open it. That direct change to the homepage is exactly what’s described. The other possibilities don’t fit typical hijacker behavior: it isn’t usually that the browser never changes homepages, that it runs faster, or that it cannot access any websites. The defining clue is the automatic homepage change, which points to a hijack.
