The issue never ever is related to a computer virus.

Open a new thread for this question.

Regarding this thread, "Make sure SSL encryption is enabled for the
incoming and outgoing mail server" -

Consider to post all POP and SMPT settings the account's of Thunderbird
and Claws are using now. What authentication is used, is non-blocking
SSl used etc.?

Is an Internet connection established at all? Can you ping a website, as
described by a previous reply?
