I copied your sudo link and launched the Terminal application, put in my password (I'm an admin) and this is the line that appeared below:
I rebooted, and launched Keychain Access. The System keychain had no invalid certificates, but it hasn't since I deleted them. I also looked over all the files in Keychain and found one for www.amazon.com among the many. Should I delete that?
Unfortunately, now when I open Amazon, it has again lost most of its functionality and I get error messages immediately.

I couldn't get in to my Amazon account eitther . . . for several days. Wrong password, it said. I reported it to Amazon, and it turned out that someone had hacked my account,and locked me out of logging in. I was lucky, however, the only thing fraudulently ordered was a 52" TV, scheduled for delivery to an address in Florida,, where I don't live.
While they were about figuring out what to charge on my bank account on file with Amazon, I was unable to log in.
That's what I meant. Not what you ordered, but what someone else could have.

Clearly, nothing is wrong with your Amazon account, because you can log into it from another device. It's also clear that the problem doesn't reside in your user account on the Mac, or in the network. We've ruled all that out.
Let's now try restoring the System keychain from a known-good backup. This is a last attempt at a precise fix. If it doesn't work, you're going to have to reinstall OS X.

I followed your instructions and restored from the beginning of November 2012. I made sure to REPLACE the current file with the earlier one from Time Machine.
When I checked the System keychain, the two certificates that I had deleted were not there.
I decided to try again, using your /Library/ link above.
This time the Finder window showed me two System keychain files, one called System.keychain / today, 9:16 PM (this one was highlighted), and the other called System.keychain.2013-02-02.21/16/15 / June 7, 2011.
I decided not to run Time Machine again, but rather just give you the above information.

By "extra" I assume you mean the second one, dated June 7, 2011?
Should I then attempt to run Time Machine again in order to repopulate the System keychain with the two missing certificates, or are we forgetting about them?
I'm signing off for the night, and will check back tomorrow for your reply.
Again, THANK YOU for your incredible support and persistence.

I did as you asked (removed the extra System keychain). Now there are just the two valid certificates I mentioned before: Apple Code Signing Certification Authority and Software Signing.
You didn't mention if you want me to try again to reintroduce the two corrupt ones that I deleted, using Time Machine.
Unfortunately, I just went to Amazon and had functionality problems again. This time listening to tracks cut off in the middle and I got the error message. When I tried to return to the site, I got the same Safari warning about an invalid certificate as before: www.amazon.com.br.
I checked the System keychain again but there are no invalid certs.
Other than my being able to log in (and that could break down any minute), I'm back to square one.
Anything else we can try before I reinstall OS X?
If not, are you sure that will solve the problem? And would you be kind enough to point me towards some good documentation for the task so I'll have some guidelines when I do it?
Thanks again for your efforts, I really appreciate it. If nothing else, I've learned a lot about my Mac in this process.

I downloaded Firefox, and here's what happened:
I went to Amazon and logged in normally. Things started off fine, but after a number of random clicks, up came this message from Firefox:
"This Connection is Untrusted. You have asked Firefox to connect securely to www.amazon.com, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are to the right place. However, this site's identity can't be verified."
I asked for the underlying Technical Information, and it said this:
"www.amazon.com uses an invalid security certificate. The certificate is only valid for www.amazon.com.br
(Error code: ssl_error_bad_cert_domain)"
Same issue as before!
What do you make of this?

I think this has gone on long enough. Back up all data, then boot from your installation disc by holding down the C key at startup. Reinstall OS X. After rebooting, run Software Update. You may have to run it more than once to get all available updates.
Test. If you still have the problem, boot from the installation disc again, but this time erase the boot volume in Disk Utility. Then install again. When you reboot, you'll be given the option to restore your data from a backup. Choose to restore user data, settings, and applications -- not "other files."
