On pourrait penser qu’à force de se perfectionner, les systèmes de nos appareils sont désormais complètement protégés contre les virus. Or, ça n’est pas du tout le cas et il est malheureusement toujours recommandé d’installer un antivirus sur son PC. Les menaces sont aujourd’hui multiples. Aux logiciels espions et virus « traditionnels » sont venus s’ajouter les chevaux de Troie, et plus récemment des menaces comme les rançongiciels qui chiffrent les fichiers des utilisateurs pour les rendre inaccessibles à moins de payer une rançon. Les détournements de sites web via des domaines frauduleux, le hameçonnage, les arnaques en ligne sont légion aujourd’hui, comme encore récemment avec la recrudescence des arnaques au SAV qui permettent aux cybercriminels de prendre le contrôle des PC ciblés. Certains logiciels malveillants s’installent sur votre système pour l’utiliser afin de « miner » des cryptomonnaies, bref les attaques sont multiples et il reste important de se protéger correctement.

Antivirus: How to make your choice?

To choose the right antivirus, it is essential to observe a few rules. The most important is to favor software that offers several types of protection. If an antivirus only protects your known virus computer, protection will be too low, as it is necessary to also be able to identify malware that is not yet known to the bases. How is this possible? For example by monitoring the activity of your computer. If the antivirus detects that software that it does not know, or which is proven as a suspect modifies files on your computer, it can alert you. It must also be able to protect you from other types of threats such as phishing which is a technique based solely on false sites or emails to deceive the vigilance of the user. Finally, it must have tools that allow you to make online purchases in a secure manner, for example by preventing pirates from intercepting what you type on your keyboard.
