Explorer.exe has generated errors and will be closed by Windows

Super Steve

I'm using Windows 2000 with SP4.

I managed to get some spyware installed in my computer. I think it was
called "vcodec", a fake video codec. Using Spybot and Ad-Aware I
managed to remove the spyware.

Unfortunately now whenever a click on an .mp3, .avi or .mpg file within
Explorer I get an error message saying "Explorer.exe has generated
errors and will be closed by Windows", and Explorer then restarts.
Just clicking on any of these files, either left or right click, is
enough to cause this error.

The Event Viewer shows the following:

I can open these three file types directly from within Windows Media
Player without any problems, just not from within Explorer.

I suspect that my codecs may be damaged somehow. However I have been
unable to find out which one. I assume that when you click on an .mp3,
..avi or .mpg Explorer searches for suitable codecs in order to show you
the preview. This only happens when I have "Enable web content in
folder" selected under "Folder options" within Explorer, which is when
Explorer wants to show a preview of the file.

I've used GSpot to get a list of all my installed video and audio
codecs. For audio codecs it reports:

I don't believe Windows Explorer cares what codecs are used or going to be
used based on extension file.

Check to see what default application is used Windows Explorer to open these
files. It may have been changed, since you can open them directly with
Windows Media Player and they play fine.

Also, in Windows Media Player, check to see what extensions it processes. I
believe it's under Options | Files. There is a list for all extensions
managed by Media player.

I'm using Windows 2000 with SP4.

I managed to get some spyware installed in my computer. I think it was
called "vcodec", a fake video codec. Using Spybot and Ad-Aware I
managed to remove the spyware.

Unfortunately now whenever a click on an .mp3, .avi or .mpg file within

Thanks for your reply.

The default application for opening .mp3 files is set to Windows Media
Player.
The default application for opening .avi files is set to Zoom Player.
The default application for opening .mpg files is set to Zoom Player.

This is as I expected.

In Windows Media Player, under Options -> Fiel Types, "MP3 audio file
(mp3)" is ticked and "Movie file (mpg)" is unticked. This is as I
expected as I use Zoom Player for viewing movies.

Any other suggestions?

Try this (I had this problem with Nero)

1. Open Regedit
2. Open key: HKEY_CLASSES_ROOT\Applications\shell
3. See if you have a sub-key named open or play. If so, check what command
(sub-key under open/play sub-keys), and see what is used to open/play.
4. Still same what you think it should be?

Next, look at:

1. Open key: HKEY_CLASSES_ROOT\mp3file\shell\play\command

and see what is set for play.

Do the same for HKEY_CLASSES_ROOT\avifile\shell\play\command and
HKEY_CLASSES_ROOT\movfile\shell\play\command

On my system, I have no movfile\shell\play\command so I can't check.

It was vccodec and it was in reality a ZLob Trojan installer.

Click to expand...

I don't have HKEY_CLASSES_ROOT\Applications\shell

The only thing remotely like "shell" under
HKEY_CLASSES_ROOT\Applications is "shell32.dll"
Next, look at:

1. Open key: HKEY_CLASSES_ROOT\mp3file\shell\play\command

and see what is set for play.
Click to expand...

It's set to "C:\Program Files\Windows Media Player\wmplayer.exe"
/prefetch:6 /Play "%L"
Do the same for HKEY_CLASSES_ROOT\avifile\shell\play\command and
Click to expand...

It's set to: "C:\Program Files\Windows Media Player\wmplayer.exe"
/prefetch:8 /Play "%L"
HKEY_CLASSES_ROOT\movfile\shell\play\command
Click to expand...

It's set to: "C:\Program Files\Windows Media Player\mplayer2.exe"
/Play "%L"

Everything looks good there. I do have Nero 6 Ultra Edition installed.
Why did you suspect Nero?

I've seen this problem many a time and this always fixed it.
Explorer runs into problems trying to generate the left pane preview.

There is one item with an error:

VFW VIFP VFAPI Reader Codec 1.05 ** Unknown VFW Driver file missing

I tracked down this codec and reinstalled it, but still GSpot reports
the error. However I don't think this is the cause of my problem.

Does anyone have any ideas as to what my problem may be?

Set the "Folder View" to "Windows Classic".
I've seen this problem many a time and this always fixed it.
Explorer runs into problems trying to generate the left pane preview.
Click to expand...

Yes, that does indeed prevent the problem from happening, but I quite
like having the preview pane, especially for previewing images (it's
not quite so useful for video).

I managed to fix my problem by uninstalling Windows Media Player,
restarting my PC, then downloading and installing Windows Media Player.

Everything seems to be working ok now.

Yay!
