Malware, short for malicious software, refers to programs designed with harmful intentions for your ordinateur^[1] system. This includes a wide range of harmful software, like viruses, worms, rootkits, backdoors, and ransomware. These programs can spread via emails, infected files, or even specific security^[2] gaps in your network. Malware is a serious threat because it can steal personal, financial, or business information, and can severely harm system performance. To fight malware, we use antivirus software that scans for suspicious code or behavior. However, it’s not foolproof. To boost your protection against malware, it’s crucial to regularly update your software, educate yourself about online safety, and backup your data regularly. Malware, while harmful, can be managed with the right strategies and tools.

Définitions des termes

1. ↑ ordinateur. Un ordinateur est un appareil sophistiqué qui manipule des données ou des informations conformément à un ensemble d'instructions, appelées programmes. De par leur conception, les ordinateurs peuvent effectuer un large éventail de tâches, allant des simples calculs arithmétiques au traitement et à l'analyse de données complexes. Ils ont évolué au fil des ans, depuis les outils de comptage primitifs comme le boulier jusqu'aux machines numériques modernes. Le cœur d'un ordinateur est son unité centrale de traitement (UC), qui comprend une unité arithmétique et logique (UAL) pour effectuer les opérations mathématiques et des registres pour stocker les données. Les ordinateurs disposent également d'unités de mémoire, comme la ROM et la RAM, pour stocker les informations. Les autres composants comprennent des dispositifs d'entrée/sortie (E/S) qui permettent d'interagir avec la machine et des circuits intégrés qui améliorent la fonctionnalité de l'ordinateur. Des innovations historiques majeures, comme l'invention du premier ordinateur programmable par Charles Babbage et le développement du premier ordinateur numérique électronique automatique, l'ordinateur Atanasoff-Berry (ABC), ont grandement contribué à leur évolution. Aujourd'hui, les ordinateurs alimentent l'internet, relient des milliards d'utilisateurs dans le monde entier et sont devenus un outil essentiel dans presque tous les secteurs d'activité.

2. ↑ security. Security, as a term, originates from the Latin 'securus,' meaning free from worry. It is a concept that refers to the state of being protected from potential harm or threats. This protection can apply to a wide range of referents, including individuals, groups, institutions, or even ecosystems. Security is closely linked with the environment of the referent and can be influenced by different factors that can make it either beneficial or hostile. Various methods can be employed to ensure security, including protective and warning systems, diplomacy, and policy implementation. The effectiveness of these security measures can vary, and perceptions of security can differ widely. Important security concepts include access control, assurance, authorization, cipher, and countermeasures. The United Nations also plays a significant role in global security, focusing on areas like soil health and food security.

According to Symantec's 2018 Internet Security Threat Report (ISTR), malware variants number has increased to 669,947,865 in 2017, which is twice as many malware variants as in 2016. Cybercrime, which includes malware attacks as well as other crimes committed by computer, was predicted to cost the world economy US$6 trillion in 2021, and is increasing at a rate of 15% per year. Since 2021, malware has been designed to target computer systems that run critical infrastructure such as the electricity distribution network.

The defense strategies against malware differ according to the type of malware but most can be thwarted by installing antivirus software, firewalls, applying regular patches, securing networks from intrusion, having regular backups et isolating infected systems. Malware can be designed to evade antivirus software detection algorithms.
