OP, invalid security certificate is something you should NOT be seeing and should NOT take lightly.
Did it inform if you who the publisher of the certificate was? If it was a unknown publisher you need to assess this issue immediately.
Your ARP table may have been poisoned, which more or less means that someone may be monitoring the information on your network.
I would recommend ensuring that your router is 100% secure, and has a good password and is not using WEP encryption. IF you do not want to research
how to fix all of this, find professional help immediately.
This could also happen by a trojan, etc. Google.com should not be displaying bad security certificates period. If you are using a unprotected(no
password/encryption) wireless connection you need to cease and desist immediately as any information you're posting over the the wireless connection
is EASILY obtainable by even the most infantile hackers.
You need to address this issue by securing your internet connection, making sure wireless has a password, etc. If you are unable to do this, request
professional help immediately. And do NOT enter ANY important information you may have right now, IE: Facebook, Email, Baking.
Let me know if you cannot get any professional help.
