How do you deactivate a Yahoo email account?

I got an email from YAHOO that says my account has virus, will deactivate account?

• In the email they are asking for my email and password. I sent an email asking them if it was legitimate. If not I would report them to the genuine YAHOO and take legal action. I need to know if this is a scam

• Answer:

  100% scam. That is a scammer trying to hi-jack your email address to spam all your contacts and then use the account to spam hundreds/thousands of others. Yahoo and all email companies, all banks and all companies in the entire world will NEVER ask for your password, pin or date of birth. No Exceptions Ever. Ignore and delete that email and any others demanding such information. If you have responded to a scammer, you are on his 'potential sucker' list, he will try again to separate you from your cash. He will send you more emails from his other free email addresses using another of his fake names with all kinds of stories of needing your password, great jobs, lottery winnings, millions in the bank and desperate, lonely, sexy singles. He will sell your email address to all his scamming buddies who will also send you dozens of fake emails all with the exact same goal, you sending them your cash via Western Union or moneygram. Do you know how to check the header of a received email? If not, you could google for information. Being able to read the header to determine the geographic location an email originated from will help you weed out the most obvious scams and scammers. Then delete and block that scammer. Don't bother to tell him that you know he is a scammer, it isn't worth your effort. He has one job in life, convincing victims to send him their hard-earned cash. Whenever suspicious or just plain curious, google everything, website addresses, names used, companies mentioned, phone numbers given, all email addresses, even sentences from the emails as you might be unpleasantly surprised at what you find already posted online.
