最近电脑奇怪地出现PF使用率特别高的情况，总是提示WINDOWS虚拟内存值太低，D盘总是出现右键菜单中有“自动播放”选项，双击D盘图标就会出现找不到command.com文件什么的窗口。进程中有一个叫“LSASS”的占用内存特别大（这个名字是完全大写的，还有一个小写的“lsass"的占用内存并不多。把“LSASS”强制关闭之后PF使用率就会恢复正常。用了瑞星在线杀毒和金山都没有查到毒。

重装系统之后（而且因为原先分区不合理的原因这次把所有硬盘重新分区格式化了）刚刚安装了腾讯浏览器（是从腾讯官网下载的最新版本）结果反应很慢而且经常就是死机不动了。PF使用率又升高到了480+，比重装之前的800+已经好很多，但是又开始提示WINDOWS虚拟内存值太低，而且这次进程中也没有那个叫“LSASS"的了。D盘已经正常，反而是移动硬盘（G、H、I）中的H盘又出现了一样的状况，总是有“自动播放”选项。

求助求助~~

如果你的系统还原从未关闭过，我建议你用系统还原解决问题
开始，程序，附件，系统工具，系统还原，把系统还原到最早的一个还原点。

你的系统很可能不止一个LSASS.EXE这么简单
看一下LSASS.EXE病毒的帖子

木马Trojan.Agent.awa的手工查杀流程：

2、结束木马进程C:\windows\LSASS.EXE。（请到www.27814939.ys168.com下载诺顿进程管理器终止C:\windows\LSASS.EXE的进程）
3、删除木马文件（见附图）
4、重启。清理注册表：
先将RegFix或SREng的后缀改为.com 或.bat，再运行之。（恢复HKEY_CLASSES_ROOT\.exe的键值）。（或到C:\WINDOWS找到regedit.exe，将其它改名为regedit.com）
展开：HKEY_CLASSES_ROOT\Applications\iexplore.exe\shell\open\command
将@="\"C:\\Program Files\\Internet Explorer\\INTEXPLORE.com\" %1"改为@="\"C:\\Program Files\\Internet Explorer\\INTEXPLORE.exe\" %1"
展开：HKEY_CLASSES_ROOT\CLSID\{871C5380-42A0-1069-A2EA-08002B30309D}\shell\OpenHomePage\Command
将@="\"C:\\Program Files\\Internet Explorer\\INTEXPLORE.com\" %1"改为@="\"C:\\Program Files\\Internet Explorer\\INTEXPLORE.exe\" %1"
展开：HKEY_CLASSES_ROOT\ftp\shell\open\command
将@="\"C:\\Program Files\\Internet Explorer\\INTEXPLORE.com\" %1"改为@="\"C:\\Program Files\\Internet Explorer\\INTEXPLORE.exe\" %1"
展开HKEY_CLASSES_ROOT\htmlfile\shell\open\command
将@="\"C:\\Program Files\\Internet Explorer\\INTEXPLORE.com\" -nohome"改为@="\"C:\\Program Files\\Internet Explorer\\INTEXPLORE.exe\" -nohome"
展开HKEY_CLASSES_ROOT\.exe
删除WindowFiles
展开HKEY_CURRENT_USER\Software\VB and VBA Program Settings\Microsoft Soft Debuger\Settings
删除"GUID"="{BI5AP8-6K55T9-8LJY6K-64M1EC-LTW624}"
展开HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
删除Top
展开HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
删除wextract_cleanup0

为了进一步确认
请下载 System Repair Engineer，使用“智能扫描”，按下“扫描”按钮进行扫描，扫描完成后按下“保存报告”按钮保存报告日志文件（SREng.LOG），把保存的报告日志文件内容复制-粘贴上来

还有，刚才看一个文章上说改注册表解除D盘自动播放的，结果改了忽然又变成所有的目录右键菜单里的第一项都成了“搜索”

按以上的方法不能解决吗
帖子看不出问题来
运行(双击)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。
