在启动选项时出现了，请问怎么办？

那提示框是缘于这一项
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Windows]
<AppInit_DLLs><KB2357802.LOG
请问你是否这样做了

关闭所有浏览窗口以及一些不必要的程序
运行Hijackthis，扫描结束后在下列选项前打上勾，然后选"修复
O20 - AppInit_DLLs: KB2357802.LOG

最后删除C:\WINDOWS\KB2357802.LOG

运行System Repair Engineer，使用“系统修复，文件关联，勾选“全选”点“修复”使所有扩展名都恢复正常。

太谢谢了，
请问我这是什么情况？病毒吗？
