1.For a specific SharePoint group, please run below PowerShell.

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue  

$GroupName = "group name"  

$SiteColl = Get-SPWebApplication  "web application URL" | Get-SPSite -Limit All | Get-SPWeb -Limit All  

ForEach($_ in $SiteColl) {  
If($_.SiteGroups[$GroupName] -ne $null)  
{  
$_.SiteGroups.Remove($GroupName)  
}  
}  

2.For a specific AD group, please run below PowerShell.

Note: Go to site settings -> Site permission -> Select the AD group -> Find the AD group account.

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

Function Delete-UserFromAllSites([string]$WebAppURL, [string]$UserAccount, [bool]$ScanOnly)  
{   
   $WebApp = Get-SPWebApplication $WebAppURL  

   foreach ($Site in $WebApp.Sites)  
   {  
    try  
      {  
      $ErrorActionPreference = "Stop"  
      $User = $Site.RootWeb.SiteUsers | Where-Object {$_.LoginName -eq $UserAccount}        
      if($User -ne $null)  
      {  
          $Site.RootWeb.SiteUsers.Remove($UserAccount)  
          Write-Host "User Deleted from: $($site.Rootweb.URL)"         
      }  
    }  
    catch  
           {   
              #Write error message on screen and to a LOG file  
              write-host "Error Deleting user from site collection: $($site.rootweb.url)"  
           }  
          finally  
          {  
              $ErrorActionPreference = "Continue"  
              $site.Dispose()  
          }  
   }  
}  

Delete-UserFromAllSites "web application URL" "AD group account" $true
