Which sort of trojan infects this server?

In computer science, a zombie is a computer connected to the Internet that has been compromised by a

hacker, computer virus or trojan horse and can be used to perform malicious tasks of one sort or another under remote direction. Botnets of zombie computers are often used to spread e-mail spam and launch denial-of-service attacks. Most owners of zombie co

mputers are unaware that their system is being used in this way. Because the owner tends to be unaware, these computers are metaphorically compared to zombies. A coordinated DDoS attack by multiple botnet machines also resembles a zombie horde attack.

B: Turtle Trojans are about getting backdoor access to an intruder.

C: A Banker Trojan-horse (commonly called Banker Trojan) is a malicious program used in an attempt to obtain confidential information about customers and clients using onli

ne banking and payment systems.

D: Ransomware is a type of malware that can be covertly installed on a computer without knowledge or intention of the user that restricts access to the infected computer system in some way, and demands that the user pay a ra

nsom to the malware operators to remove the restriction. Some forms of ransomware systematically encrypt files on the systems hard drive, which become difficult or impossible to decrypt without paying the ransom for the encryption key, while some may simp

ly lock the system and display messages intended to coax the user into paying. Ransomware typically propagates as a Trojan.
