通過腳本對 Microsoft Security Essentials 進行上次定義更新的時間戳

有沒有辦法通過 VBScript 或 Powershell 來檢查這個？我已經簡要地查看了SecurityCenter和SecurityCenter2WMI 類，但它們看起來都不是特別有用。似乎最簡單的方法是通過 WMI 中的後者確定什麼值，productState以獲取一些意味著 AV 認為沒問題的消息。 還有其他想法嗎？

您可能需要根據已安裝的版本更改 FCS_REGKEY_ROOT。這適用於最新版本。從這里拉出來的。

Option Explicit
const FCS_REGKEY_ROOT = "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Antimalware"

Dim SCAN_KEY, SIGNATUREUPDATES_KEY

SIGNATUREUPDATES_KEY = FCS_REGKEY_ROOT & "\Signature Updates"
INSTALL_PATH_VALUE= FCS_REGKEY_ROOT & "\InstallLocation"

AS_VERSION_VALUE= SIGNATUREUPDATES_KEY &"\ASSignatureVersion"
