Final answer:
Pharming is not a virus category, but rather a type of cyber attack where a user is redirected to a fake website without their knowledge or consent.
Step-by-step explanation:
The correct answer is D) Pharming.
Pharming is not a virus category, but rather a type of cyber attack where a user is redirected to a fake website without their knowledge or consent, often to obtain personal or financial information. It is not a type of virus, but rather a method used by cybercriminals to exploit vulnerabilities in a user's browsing habits.
On the other hand, worms, logic bombs, and macros are all categories of viruses. Worms are self-replicating programs that spread from computer to computer, logic bombs are malicious code that executes when certain conditions are met, and macros are sets of instructions or commands in a program that can carry out a series of actions.
