the MAILSCANNER section of my avast4.ini contains the following
PopListen=127.0.0.1:110
SmtpListen=127.0.0.1:25
ImapListen=127.0.0.1:143
Are these a hangover from the previous use of localhost 127.0.0.1 as the pop3 and smtp servers or are the 127.0.0.1 entries correct?
Leave them there, everything is under control… 
Hetzer, like Sasha said, they’re most probably right…
Which is your operational system?
Which email program do you use?
Windoze XP Pro and Mozilla with a prescan spam cleanout from Mailwasher.
hetze, it’s ok… Like Sasha said, no need to worry. These are the correct settings
