Explorer.exe problems

[Beast_]

IT seems that everything I do on my computer, such as viewing and trying to delete files.. accessing them, etc.. it causes explorer.exe to go to 99% cpu usage, thus lagging my computer to bits. Can anyone help?

Any environmental changes and things you were doing when you noticed before/during/after the problem?

I have a hunch it could be spyware related.

If none of the above fix it -

If you have.AVI files and Divvx -

Go to Start/Run/ type regsvr32 /u shmedia.dll

OR download this http://download.divx.com/divx/DivX521XP2K.exe

See HERE

--------------

If the freeze occurs when your right clicking -

It`s usually a faulty Explorer shell extension put in the right click menu problem.Known culprits include Photoshop,Divvx and Spysweeper.

1.Go to Regedit

2.Key HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers

In this key, all shell extensions are listed which work with all files. The * is a real star, it does not mean 'any key' here!

3. Choose "Registry" - "export registry", so you can revert your changes later. Choose to export only the selected branch.

4. Now delete one context menu handler after the other, and then try each time in (Windows Explorer) whether right click works again. This way you should find the defective extension.

5. When you have found it, you need to double click the .reg-file created above to restore all shell extensions, and then delete only the malfunctioning extension.

You may have to repeat this with the keys

HKEY_CLASSES_ROOT\Directory\shellex\ContextMenuHandlers

or

HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers

If the error happens with directories or with virtual folders.
