今天上網(wǎng)，輸入www.google.cn，結(jié)果網(wǎng)頁跳轉(zhuǎn)到一個類似與百度的頁面，但是網(wǎng)址卻寫的是www.yahoo.com.cn，從頁面上看，絕對不是百度的網(wǎng)頁，但是奇怪的是可以進行搜索。ping了之后發(fā)現(xiàn)三個網(wǎng)站都來之于同一個IP地址：219.235.3.16。這肯定是中了病毒或者木馬之類的東西了，結(jié)果在電腦里面找了半天，查找到了一個名為host的文件

該文件在system32/drives/etc目錄下。打開host之后，里面的內(nèi)容是：

刪除了該文件之后，結(jié)果IE正常。但是我懷疑應(yīng)該有exe或者dll文件存在在電腦里面，因為IE來讀取這個文件，而且ping命令也是讀取這個文件，但是查找半天都沒有找到。希望大家有誰遇到過類似的問題，幫我解決一下。謝謝了。
         不知道大家對這個原理了解嗎？可以探討一下！
