If you’re using Windows 2k\XP, the version 4.5 has a new mail detection that will work automatically. Please, set up your email account just as avast does not exists. It will detect the pop3/smpt/imap ports and scan your messages. Can you make a try and see if it’s ok? Thanks.

New email detection is automatic and do not require user interaction. Anyway, spam killer applications need manually change email account settings :wink: Do you use any spam killer?

If you’re using Windows 98\Me, Thunderbird must be configurated manually. Change the setting of the email accounts into Thunderbird: Menu Tools > Account settings this way:

Pop3 (Inbound):

Server name: 127.0.0.1
User name: YourUserName#YourPopServerName
Port: 110

Smtp (Outbound):
Server name: 127.0.0.1
User name: YourUserName
(or, in some systems, user name is: YourUserName#YourSmtpServerName)
Port: 25

Note, probably you should run Mail Protection Wizard to have ashMaiSv.exe automatically running at Windows startup.

Otherwise, it seems that Eddy have found a way to solve the troubles with the mail and Thunderbird (http://forum.avast.com/index.php?board=2;action=display;threadid=9069). At least it worked for this person, and may work for a lot of others also.
