遭遇Windows Update.exe/Trojan.Win32.Autoit.fc,情se发布器.exe/AdWare.Win32.Undef.eko

一位朋友的电脑最近出现了奇怪的毛病,请偶帮忙检修。

打开电脑进入Windows桌面后,感觉电脑很卡,除了超级巡警窗口,打开其它窗口都像是不停地自动在进行前台程序和后台程序的切换,一闪一闪的,很难操作。

打开任务管理器,检查进程的CPU占用率,发现CPU使用率100%,其中进程Windows Update.exe占用了70%左右。

重启电脑到“带命令行提示的安全模式”,运行pe_xscan扫描log并分析,发现如下可疑项:

pe_xscan 09-04-28 by Purple Endurer
2009-05-19 14:12:4
Windows XP Service Pack 3(5.1.2600)
MSIE:6.0.2900.5512
管理员用户组
带命令行提示的安全模式

F2 - REG: system.ini: UserInit = <C:/WINDOWS/system32/userinit.exe,C:/WINDOWS/system32/Windows Update.exe

O30 - IeOpenHomePage = "C:/Program Files/Internet Explorer/iexplore.exe" hxxp://www.52**4*16.com

另外在c:/ 发现 情se发布器.exe,WMP的图标,可疑。

用FileInfo提取文件信息,用bat_do打包备份后删除。

用HijackThis修复F2项。

O30项说明注册表中的

[HKEY_CLASSES_ROOT/CLSID/{871C5380-42A0-1069-A2EA-08002B30309D}/shell/OpenHomePage/Command,

的值被修改了,手工把后面的网址去掉就行了。
