    摘要： A Web browser or operating system of a computer maintains a historical URL list of Web sites and Web pages that have been accessed in the past. When a prescan module of antivirus software performs an initial prescan of a computer before the antivirus software is installed, it queries this historical URL list to obtain the URLs that have been accessed in the past. These URLs are sent to a URL online query service located remotely over the Internet in order to determine the status of any of these URLs. Each URL is attempted to be matched with a database of known malicious URLs including associated malicious files and associated cleanup patterns. The query service then informs the requesting computer of the status of a particular URL sent, sending back any related malicious files and any appropriate cleanup pattern. A time period associated with each URL in the database indicates when it is known that the URL was malicious.

    摘要翻译： 计算机的Web浏览器或操作系统维护过去访问过的网站和网页的历史URL列表。 当防病毒软件的预扫描模块在安装防病毒软件之前执行计算机的初始预扫描时，它会查询此历史URL列表以获取过去访问过的URL。 这些URL被发送到通过Internet远程位置的URL在线查询服务，以便确定这些URL中的任何一个的状态。 尝试将每个URL与已知恶意URL的数据库进行匹配，包括相关联的恶意文件和关联的清理模式。 查询服务然后通知请求计算机发送的特定URL的状态，发回任何相关的恶意文件和任何适当的清理模式。 与数据库中的每个URL相关联的时间段指示何时知道URL是恶意的。
