A Heads-Up For Yahoo! Messenger Users

People who use Yahoo! Messenger to video chat online with friends and family should be extra wary of incoming chat invitations from strangers. Reports suggest the presence of a previously unknown security hole in the software that attackers could use to install malicious software just by convincing recipients to accept a video chat invite.

The warning comes from anti-virus maker McAfee, which says it confirmed the existence of the flaw after reading about it on a Chinese-language security forum. The vulnerability is present in fully patched, current versions of Yahoo! Messenger (version

I congratulate McAfee on its interest on Chinese Security Forums, that means they are on their toes, as any smart business outfit should be. Back twenty years ago, when my children were about 8 years old, (20 years ago) I told my wife I wanted to take the family to China for about 7 to 10 years.

Yahoo Messenger has a lot more security flaws than mentioned. My fiancée and I, she lives in Ghana West Africa, we are constantly being blocked from chatting with each other. Suddenly we can't see what each other are typing, and we are prompted often that our id doesn't exist, and our passwords are being changed. All of my emails are removed from my accounts, and I have had more than 4 id's hijacked and taken over. Every time I sign into Yahoo messenger, I get a very strong feeling that our chat is being monitored and manipulated, she seeing thing I didn't say, and I'm seeing things she didn't type either sometimes. I am intentionally blocked from chatting with her, while I am able to chat with anyone else in the same Café where she maybe, or one or both of us changing id's.

Yahoo has so many problems on messenger, I wonder why they have it. Outside of Yahoo groups, nothing else they have works...

Why is Yahoo still in business? What do they do that someone else doesn't do better? Is it just shear size and inertia that is keeping them alive?

Yahoo Chat has been down for about a month now. Why don't they fix that? And get rid of ALL the porn bots, and the malicious booters in the rooms.
