              </p>
              <p>下载成品PPT前，按“检查网站入口—核对下载文件—扫描并检查演示文稿”三步操作；只有文件类型符合预期、扫描未发现威胁，且打开后没有要求启用宏或运行程序等异常提示，才继续使用。准备好常用浏览器、设备上的安全防护工具和一个专门保存下载文件的文件夹。HTTPS锁标志只表示连接经过加密，并不能单独证明网站可信；检查通过也不等于绝对安全。</p>

<section>
<h2>第一步：检查网站入口与下载页面</h2>
<p>先看浏览器地址栏中的完整网址，留意域名是否有拼写错位、多余字符或与页面所称来源不一致的情况。若浏览器显示欺诈网站、证书或安全风险警告，不要绕过警告继续访问，也不要在该站填写账号、手机号或付款信息。</p>
<p>打开下载页面后，检查页面标注的运营主体、联系方式、版权说明和文件介绍是否相互对应。若页面只有醒目的“立即下载”按钮，没有说明文件内容；点击按钮后不断弹出新页面、要求开启通知，或要求安装浏览器扩展和下载助手，应停止操作。免费提供模板并不代表网站一定安全，遇到强制注册或付款要求时，也先确认收费项目与下载内容是否一致。</p>
<p>操作完成的判断标准是：网址没有明显异常，浏览器未发出安全警告，页面说明与所需的PPT素材相符，且没有被强迫安装额外程序。HTTPS可以作为连接保护的一项检查，但不能代替上述判断。</p>
</section>

<section>
<h2>第二步：核对下载按钮、文件名和格式</h2>
<p>点击与目标演示文稿对应的下载按钮后，在浏览器下载列表中检查实际下载的文件名、后缀和大小，不要只依据按钮文字判断。常见演示文稿格式包括.pptx和.ppt；.pptm文件可以包含宏，应比普通演示文稿更谨慎。</p>
<p>如果按钮下载的是ZIP压缩包，先用安全防护工具扫描压缩包，再查看其中的文件清单。压缩包内若出现.exe、.msi、.bat、.scr或.js等程序或脚本文件，而页面声称提供的只是PPT，应停止解压或运行，并删除该文件。需要安装所谓“专用播放器”“下载器”才能打开PPT，也不是继续操作的理由。</p>
<p>在文件管理器中确认真实扩展名；若设备默认隐藏扩展名，可在文件管理器的查看设置中开启“文件扩展名”显示。检查完成后，文件类型应与网页说明一致，例如下载的是演示文稿，而不是名称看似“课件.pptx.exe”的可执行文件。</p>
</section>

<section>
<h2>第三步：扫描文件并以受保护方式检查</h2>
<p>先不要双击刚下载的文件。在文件管理器中选中文件，打开右键菜单，使用设备安全防护工具的扫描选项；若工具报告威胁，按提示隔离或删除，不要为了查看课件而恢复文件。若文件来自陌生来源，也不要把含有个人、工作或未公开资料的文件上传到公开扫描服务。</p>
<p>扫描未发现威胁后，再用常用演示文稿软件打开文件。若软件提供“受保护的视图”，先保持受保护状态，浏览幻灯片并检查是否出现启用宏、运行外部内容或跳转到陌生网址的提示。不要因为页面布局错乱或字体缺失就贸然点击“启用编辑”或“启用内容”；先确认文件来源、扩展名和内容都符合预期。</p>
<p>可继续使用的基本检查结果是：安全工具没有报出威胁，文件能以预期格式打开，幻灯片内容与下载说明相符，没有要求运行额外程序或启用不明宏的提示。若任一项不符合，关闭文件、删除下载项，并返回上一步重新判断；不要把“扫描通过”视为零风险保证。</p>
</section>

<section>
<h2>下载示例：用实际结果判断是否继续</h2>
<p><strong>应停止的情形：</strong>页面宣称提供一份免费课件，点击按钮后下载的却是“课件安装器.exe”，同时弹出要求安装扩展的窗口。此时文件格式与目标不符，即使页面有HTTPS标志，也应取消下载并删除安装器，不要运行。</p>
<p><strong>可以进入下一步检查的情形：</strong>页面说明提供的是某主题演示文稿，浏览器下载列表显示文件后缀为.pptx，文件管理器扫描未发现威胁，演示文稿软件也未要求启用宏。此时可以先在受保护的视图中检查幻灯片、链接和文件内容，再决定是否保存为工作副本或继续编辑；如果后来出现安全警告，立即停止使用。</p>
