1、今早一时心血来潮，去老早前的一个论坛看看不想鼠标一下子忙，偶就感觉不妙！开进程管理器，果然，2个未知进程出现！杀之，为时已晚。毒中上了。EXPLORER自动关闭，结束浏览器，结果什么也打不开了，只能用快捷键调出进程管理器，而且用进程管理器运行啥都不行（同时管理器也被关闭），用进程管理器查看关键文件夹内容，将几个新建的文件c:\windows\cguu4.exe等等的移动到其他文件夹内，尽量减少损失。

2、无奈进入安全模式，还好，没破坏。但是结果一样，光秃秃的一个桌面，进程管理器能调出，但是连CMD啥的也打不开，执行命令也无效。突然发现个问题：EXPLORER被替换了，而且有个pinyinup.exe进程占CPU100%，结束。又在SYSTEM32文件夹下看了看，发现还有个EXPLORER.EXE，属性里带签名的，看来这个是正品了！移动其到windows文件夹下，用任务管理器打开仍然失败。倒是那个pinyinup.exe又出现了（后来考虑，这个不是搜狗的问题就是被病毒利用了）！

3、这个倒是奇怪的很，不过一个念头涌现出来：我将explorer更名为pinyinup.exe放到搜狗的那个文件夹下，将pinyinup.exe更名，稍微一等，呵呵，资源管理器就出来了！但是还是不能打开任何东西（一开就结束），只能浏览文件。所以我就把wsyscheck更名放进来，过了一会也成功自动执行了。wsyscheck的功能在安全模式下受限，而且为了留下纪念，偶就把sreng更名移动了过来，执行后，扫描一份日志【见2楼】，这下偶就可以安心的清理病毒了。

删除了这三个

搞定重启，许久不见的EXPLORER终于回来了o(∩_∩)o...
进入系统后，按修改时间看了看几个关键文件夹下的文件，囧了，C盘下有个tmp.dat

4、看了看偶的临时文件夹，只DOWN了5个，还算好。再用WINDOWS清理助手扫描下，清理了些病毒残留项，至此，整个过程告一段落。呃，这次问题的出现是由于偶没装杀软（组策略也坏了）而且上了很可能有问题的网站（那个BBS以前被挂过马，而且现在鲜有人去），处理过程很简单，就是有点曲折。语文不好，希望大家不要嫌文章无味，仅作参考。

病毒样本偶都留下了，没处理掉，发到样本区去，看看有无达人玩玩。
最后囧一个，为何偶碰上的病毒都是DOWNLOADER？
