The ILOVEYOU virus (May 2000) caused estimated $10-15 billion in damages globally, infecting millions of computers via email with the subject 'ILOVEYOU'. Melissa (1999) was damaging but less widespread. Code Red (2001) targeted servers, and Chernobyl/CIH (1998) was destructive but not as economically damaging.

Antivirus software primarily uses two scanning methods: (1) Virus Signature Search - comparing files against known malware signatures, and (2) Behavioral Heuristic Analysis - detecting suspicious behavior patterns. 'Behavioral Search' is vague, and 'Pattern Search' is redundant with signatures. This covers the two main approaches.

Antivirus software primarily uses two methods: virus signature search (matching known malware patterns against a database) and behavioral heuristic algorithms (detecting suspicious activities by monitoring program behavior). Signature detection catches known threats, while heuristic analysis identifies potential new malware based on anomalous behavior patterns.

A virus hoax is a false warning about a non-existent computer virus that spreads through email chains, causing unnecessary panic. Unlike real viruses, hoaxes are purely social attacks that rely on human fear and credulity to propagate. Spoofing involves faking identities, hacking is unauthorized access, and spam refers to unsolicited bulk messages.

Cryptovirology is the study of cryptography from an attacker's perspective, including how malware can use cryptography (like ransomware encrypting files) and how to attack cryptographic systems. Kleptography is the study of stealing information securely using subliminal channels, cryptology is the broader field encompassing both cryptography and cryptanalysis, and cryptography is the practice of secure communication.

Kleptography is the study of stealing information securely and subliminally, typically through backdoors in cryptographic systems. Unlike cryptovirology (which uses cryptography for malicious attacks) or steganography (hiding existence of messages), kleptography focuses on covertly extracting information from secure systems.

Dr. APJ Abdul Kalam's full name was Avul Pakir Jainulabdeen Abdul Kalam. He was India's 11th President (2002-2007) and a renowned aerospace scientist. The key distinction is 'Pakir' not 'Pakul', and 'Jainulabdeen' not 'Jaldeen'.
