Introduction: Malware, short for malicious software, is a term used to describe various forms of harmful software designed to disrupt, damage, or gain unauthorized access to computer systems. In this article, we will delve into the world of malware, explore its different types, discuss the signs that indicate a computer may be infected, and provide prevention methods to keep your system safe.
Types of Malware: Malware comes in various forms, each with its own unique characteristics and purposes. Here are some common types of malware:
-
Viruses: Viruses are self-replicating programs that infect other files or systems by attaching themselves to host files. They can cause significant damage to a computer, leading to data loss or system crashes.
-
Worms: Worms are similar to viruses but do not require a host file to replicate. They spread rapidly across networks, exploiting vulnerabilities and consuming network resources, which can result in network slowdowns and system instability.
-
Trojans: Trojans disguise themselves as legitimate software or files, tricking users into installing or executing them. Once activated, Trojans can perform various malicious activities, such as stealing sensitive information or creating backdoors for remote access.
-
Ransomware: Ransomware encrypts files on a victim's computer and demands a ransom in exchange for the decryption key. It has become a prevalent form of malware, targeting individuals, businesses, and even government institutions.
