What is Malware?
Malware is a term used to describe any software designed to harm computer systems, networks, or devices. It can be created for various purposes, including stealing sensitive information, taking control of systems, and disrupting normal computer operations.
Types of Malware
There are various types of malware, including:
Viruses
A virus is a malicious program that infects files and programs on a computer. Once activated, the virus can spread to other computers via email, file sharing, or infected websites. Viruses can cause many problems, from simply slowing down a computer to causing significant data loss or system crashes.
Worms
A self-replicating malware that spreads over networks and the internet. Unlike viruses, worms do not require human intervention to spread. They can spread rapidly, causing significant damage to computer systems and networks.
Trojans
A Trojan is a type of malware that disguises itself as a legitimate program but is designed to perform harmful actions, such as stealing sensitive information or taking control of systems. Trojans can be spread through email attachments, infected websites, or infected software downloads.
Ransomware
Ransomware is malware that encrypts a user’s files and demands payment in exchange for restoring access. Ransomware can be spread through email attachments, infected websites, and infected software downloads.
Spyware
Spyware is malware that collects sensitive information from a user’s computer, such as login credentials, credit card details, and browsing history. Spyware can be spread through email attachments and infected websites.
Adware
Adware is malware that displays unwanted advertisements or pop-ups on a user’s computer. Adware can slow down a computer and disrupt normal operations.
Understanding the different types of malware is crucial to implementing effective malware cyber security measures and protecting computer systems and networks from cyber threats.
