Il server ha interrotto la connessione in modo inatteso. Ciò potrebbe essere dovuto a problemi relativi al server o alla rete oppure a un lungo periodo di inattività. Account: ‘@', Server: 'pop3.’, Protocollo: POP3, Porta: 110, Protezione (SSL): No, Numero di errore: 0x800CCC0F

SAME Account and same programm go ok in another PC

What OS/SP ?
What exact version of avast ?

Protocollo: POP3, Porta: 110, Protezione (SSL)
Correct me if I am wrong .... but can you use SSL on port 110 ?

Check your mail account settings, are they correct / not changed?

SSL is just a transport layer and can be used on any port as long as both sides allow it.

For POP email port 110 is the standard port used, for POP-TLS/SSL it is 995.

But the OP is not using SSL as it seems.
Porta: 110, Protezione (SSL): No

Well I moved to webmail many years ago, no such problems there and have not experienced any down time yet

sysetm is xp version is 1112245
