can anyone tell why my brother 's yahoo's nick was hacked, he said that his yahoo' nick was unable to sign in but can sign in with the other? so how can people hack his previously nick
thank youYahoo account hacked? I doubt it.
Can he log onto his Yahoo Email?no, he cant log onto his email, could it be happen if he surfs those WEBSITES with virus but he didnt know while using yahoo messenger?
cheersNot sure if it really works like that. It would have to work from inside the computer.

What Antivirus do you have?

I still doubt a virus caused this though.

Has he entered his email and password on other websites or maybe someone saw his password when he typed it in?the anti-virus is kaspersky 7 at that MOMENT, i am pretty sure that there was no one saw him typing the password and not stupid enough to enter the password in the other website, so what any other reason that that yahoo nick being hacked?
taYou can loose accounts if you allow someone else access to your computer, saved you password on your computer or on another computer (by clicking 'Remember Me' or something SIMILAR) or someone guessed your recovery question.

If someone has had access to the computer, they could have run a password recovery program (there are many many many of them out there) to find your password.

I can tell you that the chance of this being a result of someone hacking into the account is very low.

Actually....may I ask exactly what you mean when you saying 'hacked'? well, i think "hacked" account mean someone STEAL my account, is it?
can u tell me what program can hack account as u said above
well, i think for you and patio or other good at computer people , u can usually hack my account, just like , u provide me a link (with virus inside) and then i enter the web hence the virus will spread to my computer and then u can get access to my computer and use some hack program to hack my account
am i CORRECT? it 's based on my computer experience heard from outside, please amend me if i am wrong
thank you very much
