Worm.Zotob.b

影响系统:

该病毒为VC编写,Upack加壳的蠕虫病毒.通过ms05-039漏洞传播.它会创建大量的线程向目标机器发送溢出代码,造成系统性能下降,网络堵塞
并修改用户的Hosts文件,导致用户无法正常登录大量的安全网站,这给其它病毒提供了感染用户机器的机会.

1.建立一个名为"B-O-T-Z-O-R"的互斥量,如果该互斥量存在,则表示本主机已经被病毒感染,直接退出.

2.在系统目录下释放文件csm.exe

3.在注册表Software\Microsoft\Windows\CurrentVersion\Run项和
Software\Microsoft\Windows\CurrentVersion\RunServices上添加
csm Win Updates = csm.exe
使病毒能够随计算机启动而自动运行.

4. 修改注册表SYSTEM\CurrentControlSet\Services\SharedAccess start = 4 来禁止Windows自带的防火墙运行

5.修改hosts文件,使用用户无法正常登录一些安全网站
