Avast causing timeout on login to TalkTalk email server.

[Fidget]

Hi, please forgive a question from someone who may not know the correct terminology for the terms used:   
For around 3 weeks, following a change in Talktalk's email login process which changed to a non-secure password login OR since an unknown Avast update,  any attempt to login the the mail pop3 server fails on all accounts with an error "...timed out waiting for a response from the receiving server....."   
If I disable Avast complete, or the Mail shield then things work as they should. But this means that I no longer have protection on incoming mail. 
Is there a setting that I can change to suit the connection to the email server? 

Regards........Dave

Don`t know the reason for your problem......

But this means that I no longer have protection on incoming mail.

This, is not completely true

1. your mail provider may have spam/and virus scanning on the mail server. many do, like hotmail/yahoo/gmail and many more.
