删除病毒求助

今天上网，输入http://www.google.cn/，结果网页跳转到一个类似与百度的页面，但是网址却写的是http://www.yahoo.com.cn/，从页面上看，绝对不是百度的网页，但是奇怪的是可以进行搜索。ping了之后发现三个网站都来之于同一个IP地址：219.235.3.16。这肯定是中了病毒或者木马之类的东西了，结果在电脑里面找了半天，查找到了一个名为host的文件

该文件在system32/drives/etc目录下。打开host之后，里面的内容是：

127.0.0.1 localhost

删除了该文件之后，结果IE正常。但是我怀疑应该有exe或者dll文件存在在电脑里面，因为IE来读取这个文件，而且ping命令也是读取这个文件，但是查找半天都没有找到。希望大家有谁遇到过类似的问题，帮我解决一下。谢谢了。
