Explorer.exe CPU 使用率一直100% 的問題


最近電腦莫明的變很慢, 一看結果是 Explorer.exe 在搞鬼,
把它強制結束後, 再開啟 explorer , 再打開檔案總管, 不久又變成99%...

掃描電腦中並沒有中毒, 問了狐狗大神, 可能有二點原因.

中了 Win32.Poxdar, 但透過 regedit 來看跡像顯示並沒有中木馬.
很多人似乎也有相同的情況, 但不知如何解決?

您有裝什麼改變windows外觀的軟體嗎?
每次開機都是這樣嗎?
用觀景窗看見幸福的瞬間~ 用相機紀錄幸福的瞬間
請問樓主是裝哪個防毒軟體??
微軟也有出掃描後門的小程式
你可試試看
如果是中了Win32.Poxdar,版主可試著先進去安全模式,再用掃毒軟體掃毒,NORTON的病毒碼在2005/2/17的就可捉到病毒了
也可以試著灌這東西,掃駭客跟特落依的,個人覺得蠻好用的,除了有30天的試用期限制,裝完的時候,也會更新病毒碼,所以必須再上網狀態
還有記得做些windows的更新
曾經也碰過這種情形..但是怎麼解決的已經忘了..
方法一:台灣資安論壇
方法二:賽門鐵克Win32.Poxdar細項
方法三:各搜尋網站都有搜尋得到相同情形,請擇一選擇情況最類似的。
希望問題早日解決!!
感謝大家的回覆,

小弟是使用 Kaspersky AVP, 病毒碼是最新版的.
之前也發生過一次類似的情形, 但update了windows一些Hotfix之後就好一陣子,
直到昨天又一直重覆, 再開機好幾次也是一樣.
在網路上找到以下的解法, 試了一下, 竟然好了!?

真是莫名...!? 再用一陣子看看還會有什麼奇怪的情形好了.
再次謝謝大家!!

Clicking AVI Files on explorer causing 100% CPU Usage

Views: 214,601 | Avg. Rating: 4 out of 5 (1015 Votes) | Print

Well windows seem to have a REALLY big problem when it comes to reading AVI files. It seems that when you click on an AVI file in explorer, it'll try to read the entire AVI file to determine the width,height, etc. of the AVI file (this is displayed in the Properties window). Now the problem with Windows is that if you have a broken/not fully downloaded AVI file that doesnt contain this info, Windows will scan the entire AVI file trying to figure out all these properties which in the process will probably cause 100% CPU usage and heavy memory usage.

To solve this problem all you have to do is the following:

1. Open up regedit
2. Goto HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shellex\PropertyHandler
3. Delete the "Default" value which should be "{87D62D94-71B3-4b9a-9489-5FE6850DC73E}"

Voila! Please not that this will no longer provide you with the windows properties displaying the AVI file information such as width, height, bitrate etc. But its a small price to pay for saving you resources.

NOTE: Please use caution when using regedit. Improper usage may cause windows to behave imcorrectly. Also, I cannot be held resposible. Backup your registry first.
