[RESOLVED] Exchange Server - blacklisted?

All,

A laptop in our office got infected and was acting as a SPAMBOT. This blacklisted our IP address. The laptop has been quarrantined, but I do not know how to tell if the exchange server (Windows Bus Server 2003) has a trojan on it or not.

Are there any good tools out there, or tutorials on how to find this out?

Also, obviously I need to know how to go about removing trojans.

Thanks!

Dave

I've used this recently on 2 pc's that were completely borked and the owner's didn't want to format. It worked wonders. I'm assuming it'd do the same on a beefy server (if that's what you're working with).

Thanks for that, pretty decent free scanner.
