朋友說(shuō) (15:08):
方便的話，你訪問(wèn)當(dāng)年明月的 blog http://blog.sina.com.cn/m/dangnianmingyue
用sniffer看看是不是會(huì)去下載一個(gè) www.jcdh.cn/1.exe 的文件。我這只要一訪問(wèn)這個(gè)頁(yè)面就下載這個(gè)病毒。其他頁(yè)面沒(méi)事。
我不能確定是我的機(jī)器中毒了還是這個(gè)頁(yè)面有問(wèn)題。

精于心，簡(jiǎn)于形[鄭昀] 說(shuō) (15:15):
http://www.xfocus.net/articles/200610/888.html ，這里面談到了。
“兩年前,訪問(wèn)網(wǎng)站的時(shí)候經(jīng)常被重定位到北京寬帶智能糾錯(cuò)網(wǎng)站去，比較煩人。
后來(lái)一段時(shí)間好象也沒(méi)有了，也就沒(méi)有注意了。這幾天，訪問(wèn)網(wǎng)站的時(shí)候又經(jīng)常出現(xiàn)
一些奇怪的現(xiàn)象。初步判斷網(wǎng)絡(luò)有點(diǎn)問(wèn)題，當(dāng)然我能確保我的系統(tǒng)是干凈的。

朋友說(shuō):
是。我正在看xfocus那個(gè)文章，幾天前看到過(guò)。
精于心，簡(jiǎn)于形[鄭昀] 說(shuō):
我前幾個(gè)月原來(lái)說(shuō)過(guò)這個(gè)問(wèn)題，典型的流氓手段。

是，我看過(guò)你那個(gè)文章。就是互聯(lián)星空捆綁最熱的時(shí)候。

一兩年前,訪問(wèn)網(wǎng)站的時(shí)候經(jīng)常被重定位到北京寬帶智能糾錯(cuò)網(wǎng)站去，比較煩人。
后來(lái)一段時(shí)間好象也沒(méi)有了，也就沒(méi)有注意了。這幾天，訪問(wèn)網(wǎng)站的時(shí)候又經(jīng)常出現(xiàn)
一些奇怪的現(xiàn)象。初步判斷網(wǎng)絡(luò)有點(diǎn)問(wèn)題，當(dāng)然我能確保我的系統(tǒng)是干凈的。

使用環(huán)境 winxp sp2 firefox，北京網(wǎng)通ADSL撥號(hào)上網(wǎng)，使用DHCP自動(dòng)分配IP和獲得DNS，
不使用IE是因?yàn)镮E自身也內(nèi)嵌了3721查詢，正確的說(shuō)是內(nèi)嵌了auto.search.msn.com.

我們看到
??最上面的title是顯示的北京寬帶網(wǎng)－糾錯(cuò)導(dǎo)航，
??左上角使用的北京-寬帶網(wǎng)-BNN的logo,還有“溫馨提示：您輸入的域名或網(wǎng)址無(wú)法訪問(wèn)！
??????可能是輸入錯(cuò)誤，或是網(wǎng)站訪問(wèn)超時(shí)”，
??左下角是一個(gè)error.html頁(yè)面 ， http://www.jcdh.cn/error.html ，顯示
??????無(wú)法顯示網(wǎng)頁(yè)，模擬的是 Internet Explorer 找不到服務(wù)器或 DNS 錯(cuò)誤 的錯(cuò)誤。
??????(我可是用的是firefox啊)
??右邊是連接到 www.bobodogs.com 的內(nèi)容。

---------[ 0x8.1 - 影響用戶范圍 ]
??
??從51.la的統(tǒng)計(jì)上來(lái)看，影響的是北京網(wǎng)通的ADSL撥號(hào)用戶


---------[ 0x8.2 - 解決辦法 ]

??假如你比較厭煩這個(gè)東西的話，不要設(shè)置自動(dòng)獲得DNS服務(wù)器地址，自己手動(dòng)添寫非網(wǎng)通的DNS服務(wù)器。
??比如北京電信的 202.96.199.133??202.96.0.133??202.106.0.20??202.106.148.1??202.97.16.195????
