my computer is sending spam 2 my contacts-?

Sounds like your E-mail account has been compromised, or you picked up a virus, Mikey.

Immediately have your computer checked for a 'bug' or 'bugs.' If you have the proper programs, do the scans yourself, if not you need to take your computer to some one who can.

Once it is clean of pests, install a firewall and an anti-virus program if you do not have one yet.

I strongly recommend a program for malware and adware also.

After you finish this, then go in and change your password, using a good strong one.

Also, check your account information and make sure no information was changed, if it was change it back immediately.

Then, you will have to inform your contacts that it was not you sending that mail, but they need to check their computers in case they were also infected.

There may be a virus or spyware. You should scan for those. Use only reputable products. Never buy security products from spam or from pop-ups (which may themselves be generated by malware).

However, most often the spammers obtain the passwords by using phishing spam.

You do need to change your password. The spammer has it.

From a proper login to your account go to:

Options

Mail Options

Account information

You will be asked to give your password again. This is safe as long as you started from a proper Yahoo login, not a link from within a spam or other link.

From here you can change your password. However, you also want to look at the Contact Information.

You should find a Yahoo! Email that agrees with your account name. You may find a Home Email. This is an alternate contact address. There should not be one unless you entered one. If you find an unfamiliar one it could have been entered by the spammers. If they have inserted a home email under their control, they can report a "forgotten" password and collect the new password at that address.

You might want to try running an anti-virus program if you have one. It should remove it, however there are some viruses that need to be removed manually.

How do you know its you computer. someone could have gotten your account info.
