Clicking AVI Files On Explorer Causing 100% CPU Usage
Aug 12, 2002
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.

I have been having some major issues with my mouse recently - anytime I so much as move my mouse (clicking does nothing) My CPU usage for Explorer jumps up, immediatly to 50% and if I make any slightly erratic movements, up to 99% It causes major issues in quite a few games, as well as totally screwing up any multitasking I wish to do

While in Windows Explorer, if I happen to look in a folder that just contains an AVI file from my Canon S2 IS digital camera (don't even open the AVI file), DrWatson gives me a warning (can't remember the details) and then Windows Explorer hangs and have to do a CTRL-ALT-DEL to terminate W.E. and error report goes out to Microsoft. (no response of course) Happens every time.This does not happen on my notebook computer so there has to be a problem (conflict?) on this desktop.

Been having some rather strange issues with right-clicking. If I right click any executable file, my explorer.exe is killed (statusbar goes away, then appears again as explorer is reloaded) and started up again. I've been trying to figure out what could be causing it, but it's so hard to even search for a solution.

Windows XP Service Pack 2 machines with critical patches and PC-cillin Internet Security 2005 starts to experience high CPU utilization after updating to Pattern 594.If there are any administrators watching, you may want to stick this to the top of the forum for a few days.

All the .html files on mywindows XP sp2 machine have been renamed to .htm and further when I try to rename them, the explorer CPU usage suddenly increases to maximum. But, some files gets renamed and others can't be renamed at all. And, for those which cannot be renamed, I get a pop-up error message saying "file is being used by another program and cannot be renamed.", and that's when explorer starts using all of CPU and system gets very slow.I have already done full system scan through Kaspersky and Malware Bytes Anti-Malware, but they have simple turned out to be futile.

I'm running XP pro SP2. I have a gig of ram and my mother board is an Intel D101GGC. My CPU is Intel Pentium D 920.
If I use Windows Explorer to go deeper than the first level of any tree, CPU usage goes to 100% and stays there. I've disabled System Restore because it wouldn't let me go back in time anyway and this program is a known resource gobbler. Didn't help. I've attached a hijackthis logfile to see if anyone recognizes a Trojan, etc. I would appreciate any help at all.

At least twice per day Explorer.exe hogs the CPU to 99%. I can only stop it by rebooting. It has started doing so only the last two weeks or so. I use Windows XP Pro, Norton Security, Stopzilla, Counterspy, Microsoft anti spyware, Norton Ghost, Retrospect Express for my backup drive. I have a Pentium 4 2.25 Ghz, 1.5 Gb memory, Nvidia graphic card. I have searched Microsoft Knowledge Base as well as Google groups and have found no answers.

When saving a jpg image in Firefox, Firefox crashes and closes without warning. When viewing a folder full of pictures in Windows Explorer, Explorer crashes and closes in about 10 seconds (it varies). This is even when viewing the files without thumbnails (Detailed list view). I have removed Thumbs.db from this folder. I have run chkdsk /F on all partitions in my computer. This folder that is causing the Explorer crash is on a FAT32 partition. chkdsk found no errors on the FAT32 partition, but fixed something in the NTFS partition.
Even though only one folder seems to be causing Explorer to crash, it seems that no matter where I save images in Firefox, Firefox still crashes. I scanned for viruses a bit. I ran Free AVG on the entire computer. I also ran Trend Micro Housecall from the browser. No threats were found. I am using Windows XP with Service Pack 2 and all the latest updates on a Gateway MT3419 laptop.

My computer has recently been freezing quite a bit. I have re-installed the op sys win2k prof. and it still does this. I have learned to live with the freezing not a big deal i just re-start often. Anyway today it really started acting up. I get to the login screen type in my password and it loads the desktop but before i can click on anything it gives me an error message saying that explorer has caused an error and will be closed and must be re-started, then it says generating error log. At this point i click ok and there is nothing on the desktop and there is no start bar. The only button combo that works is ctrl alt del. I have tried to boot into safe mode and it does the same thing. Today i had just finished installing new updates from microsoft and it froze right after doing this so i just had to do a hard re-start could this have screwed up the op sys??

I currently have a video on my disk in a folder (yes I needed to specify this ). My problem happens when I go into this folder: windows hangs, and when I hit CTRL + ALT + DEL I see drwtsn.exe running. When I close it down exporer just restarts. This problem happens with no other video file I have. I have tried: renaming the video and the folder (done quickly before windows freezes) aswell as placing the file on another partition (though I can't do this because windows hangs when I try to move it).
I have a 'clean' computer meaning it's always kept free of viruses, spyware, adaware and all my security programs are updated and executed regularly. This problem is pretty annoying as there are other files in this folder that I can't always access in time!

I have an XPS 400 Dell computer XP Media Center Operating System. Recently my son added modzilla to our computer. In doing so he deleted internet explorer. The computer was running sluggish so I went back to a later restore date. When the computer came back up after restore only my husband and my profile were shown. while signing into my profile i get the following error message:
EXPLORER.EXE - Unable to locate component
This application has failed to start because
WININET.dll was not found. re-installing the app may fix the problem.
what do i do to get this back? There are no icons or start menue on my deskdop just my background. I can view files if i go to task manager but nothing else can be done. I know very little about computers and I need help very stressed. My kids need a computer for school.

I am having odd freezes, mostly with Windows Explorer. Windows Explorer freezes when: I right-click on any file. I try to use the 'Edit' command from the main menu, unless I am in 'My Documents' or at a higher level. I right-click Windows 'Start' button. Can I re-install Windows Explorer? Is it a registry problem?

I recently got my HP back from Best Buy, where they had to 'clean' it due to spyware, adware problems (no more Kazaa for the kids). Evidently, I had the nail.exe file, in addition to others. After 12 days, they gave it back to me, completely clean (according to them), with Norton Internet Security installed - in the process they lost all my e-mail files, but oh well. Anyway, I haven't had the darn thing back 2 weeks and I'm getting 100% CPU usage, with explorer.exe being the main hog. When I delete it in the processes list, the CPU usage goes down to 4%. I really don't want to take this thing back to BB for them to keep for another 2 weeks.

I have Windows XP, home edition. For some time now I have not been able to open files with the left double click. That highlights the title in blue allowing me to change the name. I have to open the file with right click and going to open. I have no idea how this changed and I have no idea how to change it back.

Win Xp - Service Pack 2, I suspect the problem lays with a trojan dropper. In fact I'm certain. At the moment I am getting a trojan dropper putting random files into my temp internet files every 3-4 hours - the latest file being SQL.AVG?? Norton deletes it as soon as it appears but I'm certain its causing my 90-100% CPU usage on explorer. exe. Its been doing this for about the last week.
I've got all of these installed - ZoneAlarm, Norton, AVG 7.1, Ad-Aware Se and even Microsoft Anti-Virus. I updated them all and went into safe mode and ran every single one of them on full scan and none have found the culprit. When booted back into normal mode the trojan dropper has started again and cpu usage back up to 100% for explorer.exe. Basically everthing crawls after 5 or so minutes of reboot.

An interesting problem has come up recently. If I try to open My Computer to access some file or what not, instead of bringing me to the list of drives, I get a blank white space. It never loads. From here, I can Cntrl Alt Delete and clearly see that the CPU usage is at 100% and that it is Explorer that is taking up 99% of it. I end the task of opening my computer, and then I try again and everything is fine until maybe five minutes later when the problem reoccurs. I have run virus checkers and adaware and neither has shown any problem

My computer started running extremely slow. When I check the task manager it notes that the CPU usage is spiked at 100%. I checked to see what is using most of the CPU and its "explorer.exe" using about 99%.
