Trojan.Farfli木马查杀0k7ap.sys以及XXXX.sys木马病毒

近日来,为一个病毒所捆饶,特征是,启动时会提示在

c:\windows\system32\drivers\q0gk.dll

无法找到,不能加载

系统是winxp并将所有补丁打好了的,最近也没安装程序,应该不可能有奇怪的.dll找不到.

从加载未找到的.dll文件名来看,总觉得是病毒木马之类的东西.

在运行中输入,regedit,查找注册表,也找不到任何与q0gk.dll以及q0gk相关的字段.

通过google的搜索,也无法找到任何q0gk.dll之类的信息.(有三条英文的q0gk.dll信息,通过分析,好象与自己电脑没有多大关系,但也肯定与自己电脑上加载的q0gk.dll有相关联系,但没找到任何相关办法)

系统能正常启动,本机安的是Symantec AntiVirus 10的企业中文版,在系统运行过程中,会跳出0k7ap.sys的病毒木马找到的提示,但显示不能删除.

由于我在Symantec AntiVirus中设置的所有查找到的木马病毒全删除,所以也没注意到这个木马病毒是否真的删除掉, 这个病毒木马发作时会在当前浏览器窗口上再跳出一个窗口,并且还会下载类似a.exe,g1.htm,1[1].htm之类的东西.

知道自己电脑中了木马病毒,就马上通过Symantec AntiVirus查杀c盘,检查结果没有显示有任何病毒,也以为真的就把相关的病毒木马全杀了.

但是每次启动时会跳出找不到xxx.dll,并且运行IE一定时间时会跳出新窗口,以及Symantec AntiVirus的有病毒提示.并且在病毒打新窗口后,关老窗口还是关不掉的,必须关新窗口才能连老窗口一起关掉,非常烦人.

当时以为0k7ap.sys是被删除掉的,没有通过搜索c盘确定.结果些病毒一直烦了我十来天.

今天终于下决心要解决掉,通过对比系统进程,一个一个排查,最后才发现这个0k7ap.sys在Symantec AntiVirus的作用下并没有删除掉,并且类似的.sys,.dll并没有在互联网上有所记录.

最后在Symantec AntiVirus中发现了病毒类型,再在google搜索病毒类型Trojan.Farfli才真正找到了解决方法,并从搜索结果得出一个结论,这个病毒非常烦人,他会生成不同名字的.sys.dll,所以才造成先的无法在google搜索到病毒直接名字,让人灰心的结论.

找到病毒就好办了,直接删除掉就能解决问题,但安全模式也好,正常模式也好都无法删除,最后才利用工具

Unlocker v1.8.5 多国语言版才杀除这个病毒,当然,双系统能直接启动另一个系统杀死病毒.

使用方法:

安装启动后找到要删除的病毒木马位置,选择删除,并全部解除就可以了.删除后重启动,启动时提示找不到xxx.dll也不再出现,病毒也没有了,系统正常了.

Discovered: July 29, 2007
Updated: July 29, 2007 8:51:54 AM
Type: Trojan
Infection Length: Varies
Systems Affected: Windows 98, Windows 95, Windows XP, Windows Me, Windows NT, Windows Server 2003, Windows 2000

The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.

Disable System Restore (Windows Me/XP).
Update the virus definitions.
Run a full system scan.
Delete any values added to the registry.
Delete the Web sites added to the Internet Explorer Favorites menu.
Restore the default settings in Internet Explorer.

For specific details on each of these steps, read the following instructions.

1. To disable System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:

How to disable or enable Windows Me System Restore
How to turn off or turn on Windows XP System Restore

Note: When you are completely finished with the removal procedure and are satisfied that the threat has been removed, reenable System Restore by following the instructions in the aforementioned documents.

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article: Antivirus Tools Cannot Clean Infected Files in the _Restore Folder (Article ID: Q263455).

2. To update the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:

Running LiveUpdate, which is the easiest way to obtain virus definitions.

If you use Norton AntiVirus 2006, Symantec AntiVirus Corporate Edition 10.0, or newer products, LiveUpdate definitions are updated daily. These products include newer technology.

If you use Norton AntiVirus 2005, Symantec AntiVirus Corporate Edition 9.0, or earlier products, LiveUpdate definitions are updated weekly. The exception is major outbreaks, when definitions are updated more often.

Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted daily. You should download the definitions from the Symantec Security Response Web site and manually install them.

The latest Intelligent Updater virus definitions can be obtained here: Intelligent Updater virus definitions. For detailed instructions read the document: How to update virus definition files using the Intelligent Updater.

3. To run a full system scan

Start your Symantec antivirus program and make sure that it is configured to scan all the files.

For Norton AntiVirus consumer products: Read the document: How to configure Norton AntiVirus to scan all files.

For Symantec AntiVirus Enterprise products: Read the document: How to verify that a Symantec Corporate antivirus product is set to scan all files.

Run a full system scan.
If any files are detected, follow the instructions displayed by your antivirus program.
Important: If you are unable to start your Symantec antivirus product or the product reports that it cannot delete a detected file, you may need to stop the risk from running in order to remove it. To do this, run the scan in Safe mode. For instructions, read the document, How to start the computer in Safe Mode. Once you have restarted in Safe mode, run the scan again.
After the files are deleted, restart the computer in Normal mode and proceed with the next section.

Warning messages may be displayed when the computer is restarted, since the threat may not be fully removed at this point. You can ignore these messages and click OK. These messages will not appear when the computer is restarted after the removal instructions have been fully completed. The messages displayed may be similar to the following:

Title: [FILE PATH]
Message body: Windows cannot find [FILE NAME]. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

4. To delete the value from the registry
Important: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified subkeys only. For instructions refer to the document: How to make a backup of the Windows registry.

Click Start > Run.
Type regedit
Click OK.

Note: If the registry editor fails to open the threat may have modified the registry to prevent Access to the registry editor. Security Response has developed a tool to resolve this problem. Download and run this tool, and then continue with the removal.
Navigate to and delete the following entries:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_[RANDOM 1]
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_[RANDOM 2]
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\[RANDOM 1]
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\[RANDOM 2]
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Class\{8ECC055D-047F-11D1-A537-0000F8753ED1}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_[RANDOM 1]
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_[RANDOM 2]
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\[RANDOM 1]
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\[RANDOM 2] HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\IE4\"Main" = "[RANDOM]"

Exit the Registry Editor.

5. To delete the Web sites added to the Internet Explorer Favorites menu

Start Microsoft Internet Explorer
Click Favorites > Organize Favorites
Delete the Favorites added by the risk

6. To reset the Internet Explorer home page

Start Microsoft Internet Explorer.
Connect to the Internet, and then go to the page that you want to set as your home page.
Click Tools > Internet Options.
In the Home page section of the General tab, click Use Current > OK.
For additional information, or if this procedure does not work, read the Microsoft Knowledge Base article: Home Page Setting Changes Unexpectedly, or You Cannot Change Your Home Page Setting, Article ID 320159.
