what is cnpacnp.dll???

[LAByerly]

I am working on a machine (XP home SP2) that has two references to
cnpacnp.dll. One is a BHO and the orher is a Winlogon entry. The properties
on this dll say that it comes from Microsoft, but not what it is like most ms
stuff does.

This machine had many viruses and spyware that I am trying to get rid of. I
just am not sure about this one.

Any help would be greatly appreciated.

Are you sure you spelled it correctly?

Google has never seen it except here in your post.

The only Google hit for "cnpacnp" is your own post. It your spelling is
correct, then it's probably malware. If you don't want to outright
delete it, rename it "cnpacnp.dll.old" and see what happens.

Sometimes, the best thing to do with a badly infected system is to do a
clean install of Windows and re-install all of your applications from
original media/downloads (after, of course, backing up your files and
data). Install and *update* a good antivirus application on the new
system before re-introducing your backed-up data (just in case some of
the data is itself infected).

I tried the google route also. I double checked the spelling about 10 times
because I couldn't believe ther were no hits anywhere.

I am going to assume that it is something bad. I even looked on a couple of
other clean XP home systems and it is not on any of them.

Thanks for all of the help and the quick response.

It is either a Viral malware installed on your machine/client machine for
that matter and you will need to dig deep to get it rid of it or a Vundo
Variant/Zlob.
I let the Dog Sniff/fetch on two machines here to find that file, never come
back even with a feather <g>.

Try to scan this file/DLL from here:
