关注恶意软件：

• 名称：“杀毒软件”克星木马（Trojan-Dropper.Win32.Agent）
• 大小：25088字节
• 是否加壳：否
• 影响的平台：WIN9X/ME/NT/2000/XP/2003/Vista/Win7

具体表现：

感染计算机后，木马会释放以下文件到系统：

%systemroot%\TEMP\Sermon.sys %temp%\Random.bat

还会下载文件：

http://pc1.114central.com/ooo/0.exe http://pc2.114central.com/ooo/0.exe http://pc3.114central.com/ooo/0.exe http://pc4.114central.com/ooo/0.exe http://pc5.114central.com/ooo/0.exe http://pc6.114central.com/ooo/0.exe http://pc7.114central.com/ooo/0.exe http://pc8.114central.com/ooo/0.exe http://pc9.114central.com/ooo/0.exe http://pc10.114central.com/ooo/0.exe http://pc11.dy2004.com/ooo/0.exe

进入系统后，木马会首先释放一个驱动文件Sermon.sys，并将其加载为服务运行。此服务会映像劫持系统上安装的所有常见杀毒软件，强制将这些软件关闭。同时，木马还会在计算机临时目录下释放一个批处理文件random.bat，运行并删除驱动文件、木马以及批处理文件自身，不留下任何感染痕迹。获取计算机的控制权限后，已启动的服务程序会连接远程服务器，下载恶意程序到计算机本地，给计算机用户造成更为严重的损失。

专家预防建议:

•  1.建立良好的安全习惯，不打开可疑邮件和可疑网站。
•  2.不要随意接收聊天工具上传送的文件以及打开发过来的网站链接。
•  3.使用移动介质时最好使用鼠标右键打开使用，必要时先要进行扫描。
•  4.现在有很多利用系统漏洞传播的病毒，所以给系统打全补丁也很关键。
•  5.安装专业的防毒软件升级到最新版本，并开启实时监控功能。
•  6.为本机管理员帐号设置较为复杂的密码，预防病毒通过密码猜测进行传播，最好是数字与字母组合的密码。
•  7.不要从不可靠的渠道下载软件，因为这些软件很可能是带有病毒的。
