俺的英文也三脚猫；
Symantec上说的：
The batch file contains the following command
deltree /y C:\*.*
上边一行是病毒特征码，非常下做，无条件删光C：（不是男子汉大豆夫所为也，严重鄙视他！！）
Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":
Turn off and remove unneeded services. By default, many operating systems install auxiliary services that are not critical, such as an FTP server, telnet, and a Web server. These services are avenues of attack. If they are removed, blended threats have less avenues of attack and you have fewer services to maintain through patch updates.
If a blended threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services.
Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
Configure your email server to block or remove email that contains file attachments that are commonly used to spread viruses, such as .vbs, .bat, .exe, .pif and .scr files.
Isolate infected computers quickly to prevent further compromising your organization. Perform a forensic analysis and restore the computers using trusted media.
Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.
上边是一大段废话，关于系统安全的。
To remove this Trojan horse:
1. Run LiveUpdate to make sure that you have the most recent virus definitions.
2. Start Norton AntiVirus (NAV), and run a full system scan, making sure that NAV is set to scan all files.
3. Delete any files detected as BAT.Trojan.DeltreeY.
上面是Symantec教的方法：
1、升级你的病毒定义码
2、运行你的Norton AntiVirus，做全面检查。
3、删除所有检测出来的BAT.Trojan.DeltreeY文件。
上面是Symantec说的方法。你不满意我也没办法了。不过不要急，一两天之内国内的病毒软件厂商也马上会跟进，就会有结果出来的。
