hotmail nightmare

Many apologies if any of you received spam disguised as email from me from my hotmail account. It seems that something (?) came along and sent crappy emails to everyone I've ever been in contact with through that account and then proceeded to erase my entire address book. I'm now in the process of trying to get anything that is important out of that inbox (travel stuff!) and then I have to figure out how to nuke the account. So no more MSN messenger either. I'm done.
