[紧急求助]大侠帮忙,我的电脑挂了。。。
你中的很象邮件病毒W32.Chod.B@mm
他病毒长度152,204 字节,可感染Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP系统,是一个复合型邮件病毒,能够通过MSN传播,在计算机里设置后门,使用IRC通信工具远程控制,重写Hosts文件,屏蔽一些安全网站访问
他会创建以下文件到系统目录:
• cpu.dll
• [随机目录]csrss.dat
• [随机目录]csrss.exe
• [随机目录]csrss.ini
C 创建快捷方式ProgramsStartupcsrss.lnk到启动文件夹,使得每次开机病毒自动执行取得控制权。
D 每次执行时,病毒创建以下注册表项
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun"Csrss" = "%System%[随机目录]csrss.exe"
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun"Csrss" = "%System%[随机目录]csrss.exe"
HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWindows"run" = "%System%[随机目录]csrss.exe"
使得每次开机病毒自动执行取得控制权。
E病毒创建以下注册表项,作为自身识别感染标志
HKEY_CLASSES_ROOTChode"Installed" = "1"
HKEY_CURRENT_USERSoftwareChode"Installed" = "1"
F每次开机时,删除以下注册表项关闭反病毒软等软件的执行:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRunCAISafe

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRunSmcService
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRunSPBBCSvc
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRunvsmon
G 病毒修改以下注册表项先隐藏自身
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced"Hidden" = "2"
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced"SuperHidden" = "0"
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced"ShowSuperHidden" = "0"

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem"DisableRegistryTools" = "1"
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem"NoAdminPage" = "1"
J 创建以下注册表项:
