Question

Quizplus · Accepted Answer

Hackers create a botnet by infecting other people's computers with malware that allows the master computer to control them remotely. These infected computers then become "zombie" PCs following the commands of the master computer, forming a botnet. The use of Web search bots or Trojan horses may be part of the process, but the key element is the creation of a network of infected computers under the control of a hacker. Choice A and D may be possible methods for infecting computers, but they do not necessarily lead to the creation of a botnet.
