I'm running Windows XP Service Pack 2 and using the most recent version of Windows Live Messenger. A while ago I started receiving messages from a couple of friends with links to various sites, but the friends were listed as offline. The sites are usually competitions or similar. This wasn't such a huge problem until my friends started complaining that they keep getting similar messages from me- but I'm neither on line nor sending them. I've also occasionally got messages telling me I've signed in on another computer when I haven't, and 'click here to sign in again'.
I've set Messenger Options as only allowing people on my contact list to send me messages. I've been to Control Panel/Admin Tools/Services and disabled the additional messenger service. Neither of these things make a difference.
Today I emailed friends to explain and apologise, and ask them to tell me whenever they get these messages. I also changed my hotmail and messenger password- will that solve the problem now or is there something else I need to do (apart from remove Messenger)?
Thanks in advance!
