Hi Pondus, all are gmail. Don’t confuse this with the gmail that we are all familiar with. My ISP made a deal with Google to handle their email but up until now, all was fine. Now I don’t know what is responsible for my problems- avast!, gmail or my email program but no one has offered any help. My guess is avast!

Problem started about April 27. Funny things is all of my computers experience that certificate thing but now they are fine. I am left with 3 computers that misbehaved so I removed avast! from two of them and the email/certificate problem went away. I am determined to get the last computer working but I have failed at every attempt.
