What malware exists? What distinguishes worms from viruses? Do Trojan horses risk viruses and worms?
Malware is a broad term that refers to any software designed to harm or exploit computer systems and networks. There are many different types of malware, including:
-
Viruses: It is a type of malware that can replicate itself and spread to other computers. It typically spreads through email attachments, infected files, or infected software. Once on a computer, viruses can damage files, steal data, and cause other problems.
-
Worms: A worm is a self-replicating type of malware that spreads through networks without the need for a host file. Unlike viruses, worms can spread without human intervention, and they can cause damage by consuming network bandwidth or overloading systems.
-
Trojan horses: A Trojan horse is a type of malware that is visible as legitimate software. Once installed, it can open a backdoor to allow attackers to access and control the computer. Trojan horses do not replicate themselves like viruses or worms, but they can be used to deliver other types of malware.
-
Ransomware: Ransomware is a type of malware that encrypts files on a computer or network, making them inaccessible to users. Attackers then demand payment in exchange for the decryption key needed to unlock the files.
-
Adware: Adware is a type of malware that displays unwanted advertisements or pop-ups on a user's computer. It can slow down the computer and compromise the user's privacy by collecting information about their online activities.
