最新项目需要检查windows servers 2008、2012操作系统是否安装了杀毒软件，看了网上的实现方式，发现stackoverflow上有实现的方式，但是只是过滤antivius，多增加一个过滤中文词"杀毒"就能实现查询操作系统是否安装了杀毒软件。代码如下：

$computerList = "localhost"
$filter_en = "antivirus"
$filter_ch="杀毒"
$results = @()
foreach($computerName in $computerList) {

    $hive = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine, $computerName)
    $regPathList = "SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall",
                   "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"

    foreach($regPath in $regPathList) {
        if($key = $hive.OpenSubKey($regPath)) {
            if($subkeyNames = $key.GetSubKeyNames()) {
                foreach($subkeyName in $subkeyNames) {
                    $productKey = $key.OpenSubKey($subkeyName)
                    $productName = $productKey.GetValue("DisplayName")
                    $productVersion = $productKey.GetValue("DisplayVersion")
                    $productComments = $productKey.GetValue("Comments")
                    if(($productName -match $filter_en) -or ($productName -match $filter_ch)) {
                        $resultObj = [PSCustomObject]@{
                            Host = $computerName
                            Product = $productName
                            Version = $productVersion
                            Comments = $productComments
                        }
                        $results += $resultObj
                    }
                }
            }
        }
        $key.Close()
    }
}
