I didn't read the main thread so I'm not sure what happend but this sounds like the same problem I had but in reverse so I hope it wasn't my fault? My e mail was hacked a while back and started firing out odd e mails with attachments to everyone on my address book. Most of my friends immediately realised I had been hacked and let me know but I'm sure some people must of thought it was me! Basically I had to close down the account and let hotmail sort it out before re-opening it and changing my password. There has been no repeat since then but it made me realise that we should all be changing our password regularly. I have also taken alot of people off my address book and just kept the people I regularly contact. I think doing that plus changing password 3 or 4 times a year are recommended plus never open an attachment if you think the e mail is suspicious.
