I have an AOL Screen Name and use AOL instant message. I have a box popped up on my screen that says I have a Knock Knock message from ICQ number 123456789. I went to the ICQ.com page and tried to find out who this person is from the number but they have no profile. I have no idea who this person is. If I Accept this message, will this person somehow get access to my passwords and mail, etc.? I don't talk to anyone on AOL Instant Message except a girl I work with. We use AOL when our inter-company messaging system goes down. I know its not her. So how could this person sending me an ICQ even have gotten my AOL screen name?
