今天打开电脑，然后跑去刷牙洗脸，回来发现系统自动打开了一堆网页。嘿！中毒了！莫名的兴奋啊！好久没中毒了。今天哥就陪你这丫的玩玩。
关闭傲游浏览器，升级瑞星到最新，用icesword、hijackthis扫描了一下，发现可疑项E:\WINDOWS\System32\wuauclr.exe。
在分析电脑问题过程中，关闭浏览器后，每过一段时间又会自动打开网页。找到system32目录下的wuauclr.exe，发现在该目录下还有一个文件wuauclt.exe（这个是微软自动升级用的程序）。咳，病毒制作者惯用的伎俩，把程序名命名的跟微软系统文件的文件名相似到以假乱真的地步。通过查看文件属性可以发现wuauclr.exe没有文件版本信息，而wuauclt.exe有文件版本信息，显示为微软的文件，Windows update autoupdate client。
强行结束进程wuauclr.exe，系统不再自动打开网页。用瑞星扫描wuauclr.exe没有发现病毒。上传文件到irustotal进行扫描，扫描结果如下：
