I think i've been infected by some malware which is sending spam through my Outlook 2007.
2 things have made me think this, firstly gmail has blocked my IP and whenever I send to a gmail account i get the following NDR:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

SMTP error from remote mail server after end of data:

Also periodically the Avast mail scanner goes crazy for a few seconds in the system tray, flickering on and off rapidly.
As this is happening loads of .tmp files are being created in my C:\Documents and Settings\username\Local Settings\Temp folder. They all begin ADA and then have a series of random numbers e.g. AdA306E.tmp. The size of these range from 1kb to 5Mb. At last count there were over 5000 of these files in this folder and totalled about 5Gb. Outlook has been running a lot slower since this started happening and I've though of but stopped short of re-installing it for now.
I've ran a boot time scan which found and quarantined a trojan or two, i've since ran a 2nd boot time which was completely clean, i also use spybot, ad-aware, bitdefender(online) and sophos rooktit detectors and they are all currently saying i'm clean, but the tmp files keep coming and the mail scanner still goes nuts.
I've ran a repair on Office and on all my pst files.
Not sure what to do next.
I hope that someone out there can help or suggest what to try next.
I've been told it's fairly easy to unblock yourself from gmail, but want the issue fixed before I do so.
Thanks
