What Is Malware and How Does It Affect Computers and Mobile Devices?
Malware is a type of malicious software that causes damage or compromises data on computers, mobile devices, and other online equipment. It includes viruses, ransomware, spyware, worms, and more.
Viruses: Dangerous pieces of code that infect programs and are typically triggered by unsuspecting users or automated processes. They can cause serious system damage, corrupt files, and lock out computers.
Worms: These malicious programs spread quickly and widely, clogging up networks with bandwidth demands. They usually infect one machine and spread to others by connecting to them via email, instant messaging, or other connections.
Adware: These programs often appear as legitimate apps or software but are actually malware that installs bundled spyware, ad-targeting tools, and other unwanted applications on your device. They may also collect personal information, such as passwords and credit card numbers, without your consent.
Trojans: These types of malicious programs are a stealthy way for hackers to infiltrate computers, mobile devices, and other online equipment. They hide their presence and present themselves as legitimate software until they activate, at which point they download additional malware to the victim’s computer or device.
Botnets: A botnet is a network of infected machines that can carry out malware on their own and communicate with each other. They’re used by attackers to distribute malware and sabotage networks in large numbers.
Ransomware: Another form of malware, ransomware encrypts files on victims’ computers or devices and then demands payment for the decryption key. It’s an effective extortion tool, which has targeted some of the biggest organizations in the world today.
