Asegurarte de que tu antivirus<\/strong> est\u00e9 correctamente instalado, actualizado y funcionando activamente es fundamental para mantener un entorno inform\u00e1tico seguro. Los profesionales de TI y los proveedores de servicios gestionados (MSP)<\/a> a menudo necesitan herramientas fiables para verificar el estado de las soluciones antivirus en varios sistemas. Este script PowerShell proporciona una soluci\u00f3n potente y automatizada para detectar, comprobar el estado del antivirus, y exportar los resultados a campos personalizados para su posterior an\u00e1lisis.<\/p>\n

Contexto<\/h2>\n

En el panorama digital actual, la prevalencia de las ciberamenazas<\/a> hace necesaria una s\u00f3lida protecci\u00f3n antivirus. Los departamentos de TI y los MSP deben supervisar y verificar constantemente el estado de las soluciones antivirus para asegurarse de que ofrecen la protecci\u00f3n adecuada. Este script aborda un reto com\u00fan: determinar de forma eficiente qu\u00e9 software antivirus est\u00e1 instalado en un sistema, su versi\u00f3n, la antig\u00fcedad de sus definiciones y si se est\u00e1 ejecutando actualmente. Al automatizar estas comprobaciones, el script para comprobar el estado del antivirus ahorra un tiempo valioso y reduce el riesgo de error humano<\/a>.<\/p>\n

El script para comprobar el estado del antivirus<\/h2>\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

An\u00e1lisis detallado<\/h2>\n
Este script PowerShell est\u00e1 dise\u00f1ado para detectar varios programas antivirus instalados en un sistema Windows, recuperar detalles sobre sus definiciones y estado, y exportar los resultados. Admite la detecci\u00f3n de 11 soluciones antivirus comunes, como BitDefender, Carbon Black, Crowdstrike, Cylance, ESET, Huntress, MalwareBytes, Windows Defender, SentinelOne, Sophos, Vipre y Webroot.<\/p>\n
C\u00f3mo funciona<\/h2>\n
1. Inicializaci\u00f3n y gesti\u00f3n de par\u00e1metros: <\/strong>el script para comprobar el estado del antivirus comienza definiendo varios par\u00e1metros que pueden utilizarse para personalizar su ejecuci\u00f3n. Estos incluyen opciones para excluir antivirus espec\u00edficos. Verifica que se est\u00e1 ejecutando con privilegios de administrador, ya que esto es necesario para acceder a cierta informaci\u00f3n del sistema. Si el script no se ejecuta como administrador, terminar\u00e1 con un mensaje de error.<\/p>\n
2. Comprobaci\u00f3n de privilegios de administrador:<\/strong> el script para comprobar el estado del antivirus verifica que se est\u00e1 ejecutando con privilegios de administrador, ya que esto es necesario para acceder a cierta informaci\u00f3n del sistema.
