我的电脑在每天上午会出现这样一个问题：IE浏览器每隔一段时间会自动打开，然后在几秒钟之内又自动关闭。这个过程中，通常浏览器还没有完全启动，只能看见部分IE的工具栏。不过可以清楚的看见电脑把IE打开后，随后点击了“停止”按钮，之后是右击标题栏，选择了“关闭”项，这一连贯的动作间并没有时间间隔，是个连续的过程。一般的木马程序主要是弹出网页，并不会自动关闭，我不知道是什么问题。
另外，如果我手动先把浏览器打开，那通常过几分钟后它就会自动关闭。这种情况下的关闭是突然关闭，并不能看见我开始说的鼠标动作。
以上这些现象，只在上午10点之前出现。之后到晚上1、2点都不会出现这些问题，浏览器能使用正常。
10点之后这段时间，如果使用IE，它就会跳出一些网页，但不会出现IE自动关闭的情况。同时，如果我不使用IE，这些广告网页并不会自动跳出。
我用了卡巴斯基、3721、雅虎助手、超级兔子、ewido、优化大师、还有其他一些木马专杀工具和IE修复软件都不能找出问题。均显示无毒。安全模式下也不能发现病毒。在任务管理器里面能看见多个rundll32.exe 用户进程和一个rundll32.exe 系统进程。rundll32.exe 用户进程强行关闭后，它会随即出现一个新的rundll32.exe 用户进程。

问题补充：Running processes:
