Dcim.exe病毒文件感染相机SD卡处理方案
症状：数码相机SD卡中的照片目录看不到了，但是右键SD卡查看占用情况时，空间占用挺大，说明文件还在盘中。
解决方案：直接在我的电脑-》工具-》文件夹选项：不勾选隐藏受保护的操作系统文件，同时隐藏文件和文件夹中点选显示所有文件和文件夹后确定即可看到照片文件目录DCIM
杀毒方案：采用symantec等杀毒软件进行清除查杀即可。

一个朋友还来借用已久的数码相机，正好偶家后院的一些花开得正盛，于是拍了几张PP，然后导入电脑处理。
偶打开WinRAR作例行检查，打开相机记忆棒对应的L盘，不由吓出了一身冷汗，发现两个伪装成文件夹的EXE病毒文件，还多出一个名为recycled、类似回收站的文件夹，瑞星居然没有反应！
难道遇到了瑞星检测不出来的病毒？
在“资源管理器”中打开L盘，
进入 工具-》文件夹选项，取消“隐藏受保护的操作系统文件”和“隐藏已知文件类型的扩展名”前的钩，并选择“显示所有文件和文件夹”，应用，确定。
在DCIM.EXE上按右键，从快捷菜单中选择“使用瑞星杀毒”，瑞星才检测出Worm.Win32.Autorun.eyr！
