Answers
Answer:
Malicious Software refers to any malicious program that causes harm to a computer system or network. Malicious Malware Software attacks a computer or network in the form of viruses, worms, trojans, spyware, adware or rootkits . Below are three of the most common types of malware.
Virus
A computer virus can automatically create and install a copy of itself on a computer’s files, and – like a virus in humans – it can spread from computer to computer. Viruses require a host program to exist, and they are initiated when the user opens or runs this host file. Typically, this type of malware is designed only to destroy a particular computer’s files, and the extent of its damage can vary. Some viruses are simply annoying, while others can cause more serious damage that requires the attention of a Maryland virus removal professional.
Worm
Much like viruses, worms can automatically replicate and infect multiple files. Unlike viruses, they can operate within a computer without a host file and without attaching to an existing file. Many times, worms gain access to a computer via an email, while other times they enter the network through a vulnerability. Instead of targeting a single computer, worms typically seek to harm an entire network or open a backdoor for other malware.
Trojan
Named after the famed wooden gift horse Greek soldiers used to invade the city of Troy, Trojans operate in a similar fashion. They are disguised as a legitimate or even beneficial program, and once a user enables them, they infect the computer. They are not self-replicating and can only be spread by user interaction, typically through email attachments or internet downloads.
