I don't have any tips plus no idea that your account is online by itself, it would be impossible.
I feel lazy to change passwords many times. :-(
I no longer face this problem as well, it's happened a few months ago.
On the morning of one day I went to my cousin's Internet shop. I logged in to yahoo messenger to chat with friends then an hour later, I signed out and I was really sure that I've already logged out but my cousin, she sms me to asked for this point at lunch time. She said: Do I still at Internet shop somewhere? You know I was so surprised that she told me: My id was online....I immediately came to her house: Oh my god, it was real....
I have an idea!. I replied her.
We should chat with this person and tell him/her not to do so next time anyway I didn't get any responds. So second step is to change the password!. My cousin said.
Tommorrow I came to her shop again as well as I used the same computer (It happened as yesterday). I wasn't the only one who met this, my brother also. He did the way I did but didn't work anymore. (he used the same computer as mind)
Finally, we found out no one used our ids, in fact, there was something wrong with this pc.
You say: ' You was using yahoo messanger with friends then one of yours said you sent her something bad '. The computer have done by itself actually, it may got the virus...
Ex: This is my pictures during this hot summer time...Please click here to see the photos.
Is that what she got?
Sorry if i get your point wrong.
