建议使用System Repair Engineer扫描日志作为附件上传，以便于解答～ 
下载页面：http://www.kztechs.com/sreng/download.html
操作方法：
1、下载后解压缩，运行SREngLdr.EXE；
2、如果无法打开尝试把SREngLdr.EXE改名为123.com，并复制到c:\windows目录下运行；
3、依次点击【智能扫描】-【扫描】，耐心等待，扫描结束后点击【保存报告】；
4、选择保存路径，文件名保持默认，直接点击【保存】；
5、将日志文件SREngLOG.log作为附件上传，同时务必详细描述问题现象，如果有查杀不净的病毒务必提供病毒名和路径。
注意：扫描前请尽量关闭QQ、游戏、下载工具、媒体播放器等应用程序。

如果无法运行，请到http://bbs.ikaka.com/showtopic-8517758.aspx下载修改后的sreng工具
