mozilla seamonkey problem

I use Mozilla Seamonkey as my default email client.
I recently got an email with a trojan in a .zip attachment (Trojan.Win32). It got through my
provider’s filter, which is unusual.
I was convinced that it had to open this one … twit … it took ages and
a lot of work to get rid of it.

This morning the same email arrived again and got through.

However I am running Mozilla Thunderbird in tandem and AVAST antivirus there
kicked in and warned me of the danger.

Anyone know why the difference and can I do anything about it?

1st scenario: the first detection was a false positive that a virus database update in between corrected the error.

2nd scenario: the second file wasn’t identical to the first, just similar.

Are you sure your computer is clean? I mean, run avast and other protection tools scannings?

I’m not making myself clear, am I?

The question was: why did Avast pick up the virus in the attachment when I received it via Thunderbird, while it didn’t when I received the SAME EMAIL via Seamonkey.
I did not open the attachment in either case!
(I left the email on the server)

Jim, I don’t know how Seamonkey connect and process the email, but maybe it uses a protected (encrypted connection) to the same email (SSL or TSL connections). avast can’t scan protected connections.
I’m not an expert on these mail things… sorry.

[i]Here’s a link that will provide information on SeaMonkey if you’re interested:http://www.seamonkey-project.org/

Here’s a blurb on it: Web-browser, advanced e-mail and newsgroup client, IRC chat client, and HTML editing made simple – all your Internet needs in one application.

I’ve always been of the opinion that it is the mail server that determines whether or not SSL/TSL connections are required; not the email client…

Did I miss something somewhere? ???[/i]

Fully right.
