Question

Explanation:

1. A Trojan is an unauthorized program hidden within a legitimate - looking program. Worms are self - replicating and can spread without a host program. Macros are a set of instructions in software applications, and "Sparta" is not relevant here.
2. Downloading peer - to - peer files can introduce viruses as they may be infected. Viruses can be programmed to self - execute on a certain date. Opening an e - mail attachment is also a common way for viruses to spread as attachments can be malicious. So all of these can be triggers for a virus.

Answer:

1. D. Trojan
2. D. All of the above
