Essentially there shouldn’t be any entries in the SSL scanning section (as the text at the bottom of the window basically confirms), I don’t know why you have those two there. But you have to have the gmail account setting in your email client set as if avast was never in the picture.
Whilst they are there there may well be a problem. I also notice that you have them set to POP3 and SMTP, when gmail would be using IMAP normally wouldn’t it.
I have gmail but I only use it as webmail based I don’t
