what do you mean? If your personal ID has been stolen, you would need to contact the FBI. as far as making sure it doesnt happen again has less to do with your computer and more about what your doing with it (Example- who your giving your information to). As far as hacking goes, no. unless you specifically stored all your personal information in a nice open file right on your desktop, it doesnt really work like that. just in the movies.

Why would you ever what to crack a yahoo password?  Are you trying to steal someone's ID?  I had mine stolen once, and I was not happy.

Nothing, it is lost!\nDon't worry though!!!!!!\n\nIt will probably be deleted.\n\nMost people out there are very nice and will disregard.  Try sending another e-mail stating what happend.\nIf you get a loser, then contact a credit service like Equifax.\n\nMake sure to monitor for a short time.\n\nMost ID theft happends as soon as the info is collected due to expiring information.

try updating your virus scan.. very important 2 do this 1st. before running your scan.. never run 2 different scans together.. you might want 2 download a different protector, that stops hackers.. after the smoke clears and you ran your protection, then go 2 your account and change your password.. this should be done about once a month in account.. bummer eh.. i would also change my real name and put in a sreen name,, also put in a fake address.. hackers get in like a thief in the night..

i dont know but somebody might have hacked into your computer and got your password i recommend you to get another email address and tell everybody who emails you to email you to your new address  and also get any software that protects your computer and dont use the same password to prevent more hackers & viruses.

There is NO way to get it back.\nYahoo, Hotmail, Google, and some others are so secure that they will not UNDER ANY CIRCUMSTANCES reveal the password to anyone! Not even the owner of the ID.

If it is not a picture on your system --- you may be right. Someone might of hacked your account or found out somehow otherwise.  Suggestion-- get a new MSN account with a differnt passord OR just change your password to a harder one so it will be very hard to guess on your current one.

I'd run a security program as it sounds as if there's a 'Back Door' in your system which is allowing the hacker to sneak in.  This will continue no matter how many times you change your password, the only option being to close this point of access.  try running the best thing you've got, even if it's only the Norton Anti-virus provided by Yahoo.  Today it's email, tomorrow it might be your credit card # so it's in your best interest to follow this advice. Good luck.

If you can prove that your account is hacked, contact the police.  They will put you in touch with the appropriate people...

Change your password immediately, run a virus scan- and make sure your antivirus software is up to date. Do the same with your adware/spyware protection. And use a good firewall such as Zone Alarm.\n\nAnd make sure not to give ANYONE your password. It sounds to me like you've been hacked!\n\nOh yes, and if you get any strange e-mail, don't open it and especially don't respond to it: That tends to be a favored tool of Phishers, Scammers, and other assorted scums.

Well, if I understand the fractured syntax, it sound like someone already has that Yahoo ID. So you're out of luck like so many others.

Don't know.  Usually Yahoo and other sites very careful that two people don't have same ID.
