A while ago I was checking through my user accpunts on my windows xp system, and I came across a strang user account which had apparently appeared from nowhere. It was called ASP.Net Machines - Limited user account, password protected. I did not create this account and also cannot access it as it is password protected.I have no idea where it came from or when it was created or by whom. I am the only person with access to my computer apart from my 3 year old son who occasionally visits the cbeebies website. can anybody shed light on this matter and advise me as to what to do?
