The outbox contains, say, two messages I have written. When Outlook does a send, the sending status bar at the bottom sometimes shows something like 12 messages going out. I also find that often when have messages in the outbox that have attachments, they will not go out without repeated tries. I am not sure if this is connected with the first problem. I also am receiving a fair number of messages just containing a link and the sender address is people from my addressbook. I did repeated scans with Norton Internet Security which turned up nothing. I changed to Zone Alarm and when set on deep scan it found two or three bugs, at least two of them containing "remote" in their name, and ZA says it quarantined them. But the sending of extra messages besides those in the outbox continues on occasion and I am still seeing some of the link messages from some addresses in my contact list.
