Cryptic message when starting computer

When I turn on my computer, and all the chirrings and churnings that go with dial-up are over, and my desktop appears all shiny and neat, I get the following message: "ccRegVfy cannot start because ccTrust.dll cannot be found." Then it tells me that uninstalling and reinstalling the program may be the answer.

But what program?

This message only started to appear after I installed the latest Norton SystemWorks which includes Norton Password Manager. I did set up Password Manager during the installation process, and the word "Trust" in the message makes me wonder if there is a connection.

However: everything seems to be in order; all the Norton stuff appears to be working fine, and although I haven't used the Password Manager yet, it pops up when called for with no difficulty.

Of course, I may be misled by the word "Trust". Perhaps this doesn't refer to Password Manager at all. But how can I find out what it does refer to?

How can I get rid of this message which seems to be nothing but a nuisance.
