Introduction:

In the world of cybersecurity, having an up-to-date and functional antivirus software is essential to protect your systems from malware and other malicious attacks. However, it can be time-consuming to manually check the antivirus status on multiple machines. Thankfully, with PowerShell, you can create a script that automates this process and provides you with an overview of the antivirus status on all your systems.

Creating the PowerShell Script:

To create a PowerShell script to check antivirus status, you can use the Get-WmiObject command to retrieve information from the WMI AntivirusProduct class. This class provides details about installed antivirus products on a system, such as their names, status, and definitions version. You can then filter the results based on the antivirus status (e.g., enabled, disabled, or up-to-date) and display the information in a user-friendly format.

Here's an example of a PowerShell script that checks the antivirus status:

$antivirusProducts = Get-WmiObject -Namespace "root\SecurityCenter2" -Class "AntiVirusProduct"

foreach ($antivirusProduct in $antivirusProducts) {
    $name = $antivirusProduct.displayName
    $status = $antivirusProduct.productState
  
    Write-Host "Antivirus Name: $name"
    if($status -eq 397312){
        Write-Host "Status: Enabled"
    }
    else{
        Write-Host "Status: Disabled"
    }
}

Conclusion:

With the PowerShell script described above, you can easily check the antivirus status on multiple machines and identify any potential vulnerabilities. This script can save you time and provide a quick overview of the antivirus protection across your systems. Remember to regularly update and maintain your antivirus software to ensure
