Outlook 2003 trying to send by itself ?

Help ! I've just gone over to broadband (virgin), and noticed that when outlook 2003 has finished a send/receive, after a few seconds, it trys to send from one of my dial-up email accounts, even thought there is nothing in the outbox.
I run Norton, which hasnt found anything suspicious. I was recommended Ad-Aware, and its first scan found a couple of dodgy trojans, but removing them made no difference, and it didnt find anything else exept what I would describe as ordinary cookies.
Is there anywhere I can look for things that would trigger outlook ?
Any ideas gratefully appreciated, as I am very suspicious that I have a sneaky virus trying to replicate, but luckily being stopped by the lack of a modem !

Is it trying to send by itself or is a previous narrowband account set to dial a connection?
If you're worried about infection, try a few of the online scans listed here.

Are you using Outlook or Outlook Express?

I'm using Office Outlook 2003, not Express.
I've got 'scheduled send/receive' disabled.
It is a modem account that is trying to connect (unsuccessfully) via broadband.
If there is nothing in the outbox, and its set for manual send/receive, why (how !?) is it 'dialling' anyway ?

I've just run adaware (1.0.5) again and deleted all the cookies it found with no change in outlook's behaviour.
I'm running xp sp2, norton antivirus 10.0.1.13 and norton interent security 7.0.6.17, all set to auto-update.

I was recommended Ad-Aware, and its first scan found a couple of dodgy trojans....

Download, install, update and run Trojan Defence Suite 3. It's a fully functional but time limited (30 days I believe) demo and it's about the best tool available for trojan detection and removal.

Don't forget to disable any system restore type software before attempting to clean your system.

After running TDS 3 and "fixing" anything that it finds, have a look at this thread and if necessary, post a HJT! log.
