I have a workgroup of 10 computers and a about 2 months ago I had a very high upload to the net from our server. 115Kb/s. I this went on for a whiole day until it was stopped by installing a software firewall (zone alarm) as it seemed to block the ports that this was uploading trough. All was fine until last week where one of the client computers on the work group all of a sudden had a message appear from Zone Alram saying that more than a 100 emails were sent out under one minute or some short time. (this alert came about from the setting in Zone Alarm that alerts you if more than 5 email gets sent in 2 seconds.) When looking in the sent folder in Outlook Express none of these emails appeared. Looks like it was sent from another SMTP engine. The eamils that were sent did not come from any address book on the computer as far as I could see. (Our company does not have a local mail server.)
The strange thing about all of this is that we have Norman Antivirus and this is ALWAYS kept up-to-date and running in the background. I even did a hard-disk scan with Norman running the computer in safe-mode. I checked all the processes running through task manager against difrent sites on the internet and all processes seems to be valid ones.
Does anyone know??
