Understanding Cyber Safety Concepts

Cyber safety refers to the practice of protecting yourself, your data, and your devices from online threats. It encompasses various measures to ensure a secure digital experience.

Viruses

A computer virus is a type of malicious software program that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be “infected”. Viruses often require a host program to spread.

• Examples: Boot sector virus, file infector virus, macro virus.
• Prevention: Use antivirus software, avoid suspicious downloads, scan external media.

Malware

Malware is an umbrella term for any software intentionally designed to cause damage to a computer, server, client, or computer network. It includes viruses, worms, Trojan horses, spyware, adware, and ransomware.

Spam

Spam refers to unsolicited or undesired electronic messages, typically emails, sent to a large number of recipients for commercial advertising or malicious purposes. Spam often contains phishing links or malware attachments.

• Prevention: Use spam filters, do not open suspicious emails, never click on links or download attachments from unknown senders.

Antiviruses

Antivirus software is a program or set of programs designed to prevent, search for, detect, and remove software viruses, and other malicious software like worms, Trojans, and more. It is an essential tool for cyber safety.

• Key Features: Real-time protection, scheduled scans, virus definition updates, firewall.
• Best Practices: Keep antivirus definitions updated, perform regular full system scans, use alongside a firewall.
