Been where? I suggested two different places.

You can try another e-mail client to determine if the issue is the
client (or its associated settings or how it interacts with Windows 7)
or the ISP.

You could always post to the Windows 7 Web forum PA Bear mentioned if
you believe this has something to do with the OS.

Microsoft Security Essentials (MSE) doesn't include email scanning /per se/.

Did you upgrade to Win7 or are they both new computers?

When (approx. date) did you install MSE and was the computer fully-patched
at Windows Update at the time?

What anti-virus application was installed before you installed MSE, was your
subscription still current, and did you uninstall it before you installed
MSE?

Has a(another) Norton or McAfee application ever been installed on the
computer (e.g., a free-trial version that came preinstalled when you bought
it)?

Not very much useful information from OP that wasn't obtained like
pulling teeth.
I run the latest version of Thunderbird on 3 different laptops, 1-32
bit Windows Home Edition and 2-64 bit Windows 7 Home Premium,
If outgoing e-mails time out it is very likely it exceeded the time
limits set by your ISP and it is they rather than your machine. OS
version or e-mail client that is fault. Suspect a poor internet
connection.
Your ISP retains the same time constraints regardless of whether or
not the ISP is delivering fully at their "up to "X" Mbs upload speed".
So if your ISP is running slower than usual, e-mails can "time out." I
happen to have that kind of ISP(Clearwire) so I am used to this
happing from time to time on any of my machines and OS's.

I hardly think this has anything to do with which OS one is using.
XP took a long time to become about as good as it will ever be
getting.
Windows 7 is a major improvement over XP and Vista but I am very glad
the need for any new computers did not come up until Vista was canned.
XP is fine, I have no complaints. But it really is getting rather long
in the tooth.
New hardware has made XP more and more anachronistic, New OS versions
are best exploited with new hardware.
Maybe the learning curve is steeper than some care to deal with making
a transition from XP to Windows 7 but I had to learn quite a bit about
Windows 7 pretty fast when my XP machine was in a shop for repairs for
almost a month. I now use Win 7 for everything including accessing the
XP machine on my network.

My Internet provider found the problem and I will quote his response below.

""I found the issue with TB 3.0. Thunderbird defaults the outgoing mail
server port to like 573. Probably so it can cache some info on disk.
Once I changed that port to 25 it works fine.


To change it click on Tools and then accounts. Select the Outgoing
Server(SMTP) option on the left side pane. Select your account and click
on edit. Change the port number to 25.""

This is an odd quirk with Win 7 and Thunderbird 3 as a combination.
