I have win xp sp2, NIS2006 everything is completely up to date . I use yahoo messenger, yahoo mail and I visit yahoo game rooms.
Today I was on Instant Messenger with someone I considered a friend and I was discussing how a certain person was able to know I was online even when I am invisible. He told me that its possible to by running a special program to tell if someone has a webcam, what they are saying on IM what they are typing to whom and what " games " room they are in even when you have them blocked or are invisible.
I noticed a few hours before chatting with this " friend " that someone had im'd me and was asking me if I had a cam , I said no, ( I have one but don't use it ) was meant only for family out of state but have yet to use it. Anyway, this person kept insisting that I have a cam. I think its the same person I have on my list as a friend.
What I want to know is since I have a firewall and everything is up to date, I've even used black vipers suggestions to shut down unnecessary programs, I also use Mark Janssons suggestions for securing xp ( www.markusjansson.net
In it he helps you shut down the ms shares and such.. How can this person on yahoo messenger know that I have a cam, or know who I am talking to and such. More importantly how can I stop them ?
