"Windows Explorer has stopped working" message

Thats the message when I boot up. The pc will still goes to desktop and as
soon as the above message appears, I cannot click on anything on the desktop.
Right click any icon nothing happens.

Details of the message/problems as stated:-

AppCrash
Explorer.Exe
Faulty module name:- afkvvy.dll_unloaded

When I close the above message box, it will disappear and reappear. During
the momentarily disappearance, I can click the icon and say right vlick the
icon it will give a dialog box.

When I boot in save mode, pc will hang once the message appears and it will
appear even before we can see the 4 :safe mode" words at the corners.

Something must have been installed into the pc which I have no idea. Any
idea then how can I fix this problem, thanks

A Google for "afkvvy.dll" brings me nothing. This could mean that the
file belongs to malware or it could mean that the file belongs to
something legitimate that just isn't working. Since I don't know
anything about your computer and how Vista was installed (by you as an
upgrade, clean install, preinstalled on new computer), I can't guess.

So, what is the virus/malware status of the computer? If you think it is
clean, what antivirus/antispyware programs did you use to determine this?

If the machine is clean, then you can do some clean-booting
troubleshooting to see what is starting with Windows and causing the
problem:

hi ,
-- this has happened to me also ,it seemed to be a compatibility problem
with a downloaded program in my case. The only chance you've got is to do a
system restore from startup.If you are using nav2007 you wont be able to do
this without disabling norton first , you can do this using safe mode with
command prompt ihave all details from norton if needed hope this helps

Reading from other's posts and did a Superantispyware scan and deleted
whatever the outcome. Upon boot up, now the message is the "Internet explorer
is not working" and the fault module is "stackhash.dll" which cannot be clean
by spybot. I try to run housecall but it will not allow me to download the
definitions and "zero' finding.

What's the current fault information present for the current crash in the
Problem Reports and Solutions center?
