我的HP笔记本电脑出现奇怪的问题。这是最近开始发生的。每当我启动计算机时,Windows 7操作中心都会显示以下警告:
您需要重新启动计算机才能关闭UAC。
实际上,如果在特定日期发生一次,则不会发生这种情况。例如,当我早上启动机器时,它会显示出来;但在该天内的后续重启中都不会显示。在第二天,同样的事情再次发生。
我从不禁用UAC,但显然某些rootkit或病毒会导致这种情况。收到此警告后,我将立即转到UAC设置,然后重新启用UAC以消除此警告。这是一个令人困扰的情况,因为我无法解决。
首先,我在计算机上进行了全面扫描,以检查是否存在任何可能的病毒和恶意软件/ rootkit活动,但趋势科技防毒墙网络版表示未发现病毒。我使用Windows系统还原去了一个旧的还原点,但是问题没有解决。
到目前为止,我已经尝试过(找不到rootkit):
- 趋势科技防毒墙网络版防病毒
- AVAST
- Malwarebytes的反恶意软件
- 广告意识
- Vipre Antivirus
- GMER
- TDSSKiller(卡巴斯基实验室)
- HiJackThis
- 注册表运行
- UnHackMe
- SuperAntiSpyware便携式
- 泰泽Rootkit剃刀(*)
- Sophos Anti-Rootkit
- 间谍猎人4
- 组合修复
机器上没有其他奇怪的活动。除了这个奇怪的事件,一切都正常。
这个讨厌的rootkit的名字是什么?如何检测和删除它?

正如这个非常类似的问题所建议的那样,我已经使用RegRun和UnHackMe运行了完整扫描(+引导时间扫描),但是它们也没有找到任何东西。我已经仔细检查了事件查看器中的所有条目,但是没有错。
现在我知道我的机器上有一个隐藏的木马(rootkit),它似乎很成功地掩饰了自己。请注意,我没有机会删除HDD或重新安装OS,因为这是一台受公司域上某些IT策略约束的工作机器。
尽管做了我所有的尝试,问题仍然存在。我严格需要点对点方法或pukka rootkit卸妆剂才能将其删除。我不想胡闹的系统设置,即禁用自动运行一个一个,搞乱注册表,等等。
编辑2:我发现了一篇与我的麻烦密切相关的文章:
恶意软件可以在Windows 7中关闭UAC;微软说:“按设计”。特别感谢(!)微软。
在本文中,给出了VBScript代码以自动禁用UAC:
'// 1337H4x Written by _____________
'// (12 year old)
Set WshShell = WScript.CreateObject("WScript.Shell")
'// Toggle Start menu
WshShell.SendKeys("^{ESC}")
WScript.Sleep(500)
'// Search for UAC applet
WshShell.SendKeys("change uac")
WScript.Sleep(2000)
'// Open the applet (assuming second result)
WshShell.SendKeys("{DOWN}")
WshShell.SendKeys("{DOWN}")
WshShell.SendKeys("{ENTER}")
WScript.Sleep(2000)
'// Set UAC level to lowest (assuming out-of-box Default setting)
WshShell.SendKeys("{TAB}")
WshShell.SendKeys("{DOWN}")
WshShell.SendKeys("{DOWN}")
WshShell.SendKeys("{DOWN}")
'// Save our changes
WshShell.SendKeys("{TAB}")
WshShell.SendKeys("{ENTER}")
'// TODO: Add code to handle installation of rebound
'// process to continue exploitation, i.e. place something
'// evil in Startup folder
'// Reboot the system
'// WshShell.Run "shutdown /r /f"
不幸的是,这并不能告诉我如何摆脱系统上运行的恶意代码。
编辑3:昨晚,由于运行SQL任务,我没有打开笔记本电脑。当我早上来时,我看到UAC已关闭。因此,我怀疑该问题与启动无关。无论机器是否重新启动,它每天都会发生一次。
编辑4:今天,我一启动Windows就希望立即抓住有罪的人,我立即启动了“进程监视器”(感谢@harrymc提出这个想法)。在9:17,UAC滑块滑至底部(Windows 7 Action Center发出了警告)。我调查了9:16到9:18之间的所有注册表操作。我保存了过程监视器日志文件(70MB,仅包含2分钟的间隔)。有很多EnableLUA = 0
(和其他)条目。我将在下面发布前四个属性窗口的屏幕截图。它说svchost.exe
正在执行此操作,并提供一些线程和PID编号。我不知道该如何推断他们:
