某日,一位WINDOWS管理员电话找我帮忙,说自己分身无术,自己所在的SITE有多台染毒计算机要处理,不可能花1个多小时的时间跑到我这个SITE 来处理这边的染毒计算机。并说必须引导到安全模式下处理,云云……我要来管理员的密码,通过终端服务连过去看了一下,果然用任务管理器无法杀掉 bcvsrv32.exe,但想到我要先去找键盘、鼠标、显示器还要重启计算机若干次,不禁头大,还是先试试别的办法再说吧。于是赶紧通过GOOGLE, 下载了WINDOWS平台两个管理进程的小工具tlist.exe和pskill.exe(tlist.exe可以从WIN2000光盘中的 Support Tools找到,pskill.exe可以从各个黑客工具网站下载),试了一下,没想到很快将问题搞定。于是写下了下面这个MAIL,发给公司的所有 WINDOWS管理员。
how to deal with the virus "bcvsrv32.exe" in one minute?
Someone say the virus "bcvsrv32.exe" can't be removed unless reboot the computer, but I find a easy way to deal with it.
Firstly, we need two tools named tlist and pskill. You can see them in the attachment.
Secondly, upload the two tools to the victim server. For example, you can put them to 9.184.83.79ADMIN$ .
And then, on the victim server, find out the process id of "bcvsrv32.exe". And in this case I find the pid is 2776.
Let's begin! key down the fllowing commands.
C:Documents and Settingsteserver>tlist 2776 |more
2776 bcvsrv32.exe
CWD: C:WINNTsystem32
CmdLine: C:WINNTsystem32bcvsrv32.exe -meltserver "9.184.83.79E$bcvsrv3
2.exe"

......

Please notice this line -- C:WINNTsystem32bcvsrv32.exe -meltserver "9.184.83.79E$bcvsrv32.exe".OK,
we can find the two bcvsrv32.exe files in this system. The
E:bcvsrv32.exe can be deleted easily, but when you delete
C:WINNTsystem32bcvsrv32.exe, you will only see a promotion "Access
deny".
事后注解:其实问题就在这里,如果不先对付E:bcvsrv32.exe,你就会发现进程bcvsrv32.exe永远杀不掉。会用tlist这样的命令行工具,问题也就迎刃而解。就这么简单!
Don't worry. It's the time to use the tool pskill. Follow me, please.

By the way, we need reversing the changes made to the registry. Please see this article, http://securityresponse.symantec.com/avcenter/venc/data/w32.gaobot.bqj.html .
其实,本文没什么特别的东西,只是我觉得一个合格的WINDOWS管理员必须要了解和擅长使用Support Tools、Resource Kit和一些黑客小工具。正所谓,工欲善其事,必先利其器。
