What Is Malware?

Malware denotes computer code or software surreptitiously installed and operated on a user's device without their knowledge or consent. It is crafted to carry out harmful actions, such as data theft, encryption, alteration, deletion, and surveillance, infringing upon users' legitimate rights and interests. Implementing preventive measures and enhancing user awareness can significantly decrease the likelihood of malicious software attacks, consequently minimizing potential damages.

Types of Malware

Various forms of malware encompass viruses, worms, Trojan horses, ransomware, spyware, and adware, each with distinct modes of attack and potential damage. These types are detailed below:

  • Virus: Attached to programs and activated upon opening, viruses replicate by altering other programs' code, often transmitted via malicious emails.

  • Worm: Self-replicating and spreading automatically, worms exploit software vulnerabilities to rapidly infect networks.

  • Trojan horse: Deceptively appearing harmless, Trojan horses trick users into downloading and installing them, operating discreetly once activated.

  • Ransomware: Locks or encrypts files on victims' devices until a ransom is paid, commonly distributed through malicious email attachments or downloads.

  • Spyware: Stealthily operates in the background, recording user activity such as keystrokes and web browsing without their awareness.

  • Adware: Gathers user browsing and downloads data to deliver targeted advertisements, often installed through deceptive ad clicks.
