receiving invalid or expired certificate error

i am receiving invalid or expired certificate errors in Windows xp using Internet explorer.

i had no problems going to these sites earlier this week.

ATT Yahoo help was no help at all. they had me change the browser and internet settings, but this did not work.

i even tried install the certificates, but that did not help either.

i think someone is attacking my computer

does anyone have ideas of what i can do.

do you have a firewall? Anti-Virus/spyware scanner?

Hi joehamm. Does it happen on every website or just a select few? Certificates expire. If it happens on only a few sites, it is the responsibility of the website administrator to maintain the certificates.

If it happens on EVERY website, then we can start talking about "attacks."

I can understand that you are concerned about the certificates but let me say it like this:

It is not our responsibility, as the end user, to monitor the certificates. If you receive an warning that the certificate has either expired or is invalid, that needs to be addressed by the site's webmaster, regardless of the size of the company or the date posted on the certificate.

This warning message is to let the computer user know that the site he or she is about to view does not have an updated certificate, that's it. It is then up to the user to decide if he or she wants to proceed and navigate that site.

The website's online security may have to be updated or any other number of reasons could have prompted this message. You, personally, do not have anything about which to worry. Now, if you shop on this site or if you have to access personal information, you should contact the technical support department first and let them know that you are receiving this warning message.

This is the same type of situation when you get a warning message that says that you are about to access a site that has encrypted and non-encrypted information. It is up to the user to decide whether or not he or she wants to continue.
