Il est essentiel de s’assurer que le logiciel antivirus install\u00e9<\/strong> est correctement install\u00e9, mis \u00e0 jour et actif pour maintenir un environnement informatique s\u00e9curis\u00e9. Les professionnels de l’informatique et les fournisseurs de services g\u00e9r\u00e9s (MSP)<\/a> ont souvent besoin d’outils fiables pour v\u00e9rifier l’\u00e9tat de l’antivirus sur plusieurs syst\u00e8mes. Ce script PowerShell fournit une solution puissante et automatis\u00e9e pour d\u00e9tecter les logiciels antivirus, v\u00e9rifier leurs d\u00e9finitions et leur \u00e9tat, et exporter les r\u00e9sultats vers des champs personnalis\u00e9s pour une analyse plus approfondie.<\/p>\n

Contexte<\/h2>\n

Dans le monde num\u00e9rique actuel, la pr\u00e9valence des cybermenaces<\/a> n\u00e9cessite une protection antivirus robuste. Les services informatiques et les MSP doivent constamment contr\u00f4ler et v\u00e9rifier l’\u00e9tat des solutions antivirus pour s’assurer qu’elles fournissent une protection ad\u00e9quate. Ce script r\u00e9pond \u00e0 un d\u00e9fi courant : d\u00e9terminer efficacement quel logiciel antivirus est install\u00e9 sur un syst\u00e8me, sa version, l’anciennet\u00e9 de ses d\u00e9finitions et s’il est en cours d’ex\u00e9cution. En automatisant ces v\u00e9rifications, le script permet de gagner un temps pr\u00e9cieux et de r\u00e9duire le risque d’erreur humaine<\/a>.<\/p>\n

#Requires -Version 4.0\r\n\r\n<#\r\n.SYNOPSIS\r\n    This script will attempt to detect the installed antivirus (currently supports 11) and get the age of its definitions, version, and whether or not the antivirus is currently running. It can export the results to one or more custom fields. This script is a best effort and should be treated as such; we do recommend verifying any results.\r\n.DESCRIPTION\r\n    This script will attempt to detect the installed antivirus (currently supports

Description d\u00e9taill\u00e9e<\/h2>\n
Ce script PowerShell est con\u00e7u pour d\u00e9tecter les diff\u00e9rents programmes antivirus install\u00e9s sur un syst\u00e8me Windows, r\u00e9cup\u00e9rer les d\u00e9tails de leurs d\u00e9finitions et de leur \u00e9tat, et exporter les r\u00e9sultats. Il prend en charge la d\u00e9tection de 11 solutions antivirus courantes, dont BitDefender, Carbon Black, Crowdstrike, Cylance, ESET, Huntress, MalwareBytes, Windows Defender, SentinelOne, Sophos, Vipre et Webroot.<\/p>\n
Comment \u00e7a marche<\/h2>\n
1. Initialisation et gestion des param\u00e8tres : <\/strong>Le script commence par d\u00e9finir divers param\u00e8tres qui peuvent \u00eatre utilis\u00e9s pour personnaliser son ex\u00e9cution. Il s’agit notamment d’options permettant d’exclure un logiciel antivirus sp\u00e9cifique qui aide \u00e0 v\u00e9rifier qu’il fonctionne avec des privil\u00e8ges d’administrateur, ce qui est n\u00e9cessaire pour acc\u00e9der \u00e0 certaines informations du syst\u00e8me. Si le script n’est pas ex\u00e9cut\u00e9 en tant qu’administrateur, il se terminera par un message d’erreur.<\/p>\n
2. V\u00e9rification des privil\u00e8ges d’administrateur :<\/strong> Le script v\u00e9rifie qu’il s’ex\u00e9cute avec des privil\u00e8ges d’administrateur, ce qui est n\u00e9cessaire pour acc\u00e9der \u00e0 certaines informations du syst\u00e8me. Si le script n’est pas ex\u00e9cut\u00e9 en tant qu’administrateur, il se terminera par un message d’erreur.<\/p>\n
3. R\u00e9cup\u00e9ration des informations sur l’antivirus : <\/strong>Le script utilise plusieurs m\u00e9thodes pour d\u00e9tecter les logiciels antivirus install\u00e9s :<\/p>\n
