After working on his doctoral dissertation for two years, Joe, a user, is unable to open his
dissertation file. The screen shows a warning that the dissertation file is corrupted because it is
infected with a backdoor, and can only be recovered by upgrading the antivirus software from the
free version to the commercial version. Which of the following types of malware is the laptop
MOST likely infected with?
A.
Ransomware
B.
Trojan
C.
Backdoor
D.
Armored virus
Ransomware locks your pc and it displays a message saying that the user has to pay a certain amount of money or the pc will remained locked. If the amount is paid then the attacker claims that he/she will provide the user with a password to unlock the pc in the space provided.
However there are instances were a attacker does not provide the password or the password does not work at all. So it isn’t a good idea to give the attacker the said amount of money.
As for the question I doubt that the answer could be A. The answer should be a rogue anti-virus software.
