Vista - Cant't send Email over 450MB anything under find

I have had a succesfull connection for over a year. Suddenly I can't send anything over 450 KB server time out . I can send anything under that fine. I can received fine. I get the following message:

Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Error Number: 0x800CCC0F

There does not appear to be any problem with my server. I can go online and
send from my providers site. There is no long period of inactivity and no
apparent network problems. This happen when Bellsouth switch to Yahoo last month.

450 MG.
You're funny.

I believe AT&T/Yahoo has a message size limit of 10 or 20 MB.

In that case, the problem is most likely being caused by interference
from your antivirus program. Which antivirus are you running?
As a minimum, email scanning in the antivirus should be turned off,
although that may not be sufficient to eliminate all bad effects.
In a worst case scenario, your antivirus may need to be uninstalled.

Email scanning in any antivirus should be disabled, for reasons
explained here:

If no improvement after disabling email scanning, consider upgrading
to Windows Live Mail, because it is less prone to suffering bad effects
from overly intrusive antivirus programs:

Thanks guys,
I have enable Norton 360 still time out, I have when in under run and config. and enable everything, when in internet options delete cookies history, temp.files, restarted computer still when I tryed to send anything over 450 the mail times out,
This all happen when Bellsouth (ATT) switch to Yahoo mail last month till then could send anything out I received. This is doing it on Vista and XP for I have two differ computers.
I spoke to their (ATT & Yahoo Tec.support) they said its a microsoft problem,below is sample of error:

{Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Subject 'Fw: A Fishy Story........', Account: 'pop.att.yahoo.com', Server: 'smtp.att.yahoo.com', Protocol: SMTP, Server Response: '451 timeout (#4.4.4)', Port: 465, Secure(SSL): Yes, Server Error: 451, Error Number: 0x800CCC0F}
Thanks,
