Thunderbird was working perfectly. Suddenly I started getting messages that there was unauthorized use. Then it kept blocking me from signing in even though I went to google and changed the password 2x. I still can't get email to one account that I have on a PC and a Mac. The program keeps asking me for a password and then tells me to go to the web for that account. I can log in to the gmail account just fine on the web with the new password. The gmail notices of password changes keep going to my recovery email. I have done a complete scan of the computer and hopefully cleaned anything bad off of it. I have listed my personal email on this request as I am unable to access the one in question at this time. Thank you.
