Someone keeps changing my passwords. I've changed passwords billion times a week?

[Paci]

So first it started on my twitter. I tried to log in to my twitter but it said that my password was wrong. So i clicked the forgot password thingy and checked my e-mail (please note that i have 2 yahoo IDs. The one i used for twitter is the first one), and got my twitter back.

The next day, i tried to log into my Email address (1st yahoo ID, the one i used to get my twitter password back) and i couldn't log in. The problem was the password. So i clicked the "i can't access my account" thingy, picked the "send reset password link to your alternative e-mail address" way (my 2nd Yahoo! ID), and got my 1st Yahoo ID back, that was the first time..

The next 2 days, my twitter, my 1st Yahoo ID, my alternative Yahoo ID's passwords were all changed. Same thing as my twitter incident. After an hour of moving around to get them back, i got my twitter and 1st e-mail back (I got my 1st e-mail by using the secret question way, because i couldn't open my alternative email). But after i went offline for about 2 hours, it happened again. I tried ways to get them back and got sick of it. So i backed down and tried to find any solutions for my problem. Many people say it's keylogger. But i don't really know what that is and how to remove it. Or maybe some of you know what this thing is? Other than keylogger? I've changed it million times a week but it still happens. I've tried to contact Yahoo customer care and Twitter customer care, but they haven't replied.

Please, i really need your help.
P.S: I've been trying to download Ad-aware but since my IDM was registered by a fake ID, i can't download anything=.= A little help with this too, maybe?

use another computer to log in and change your passwords.

do not use the infected computer you are on now to
log in to anything until it is cleaned.

if you are unable to download anything,
to attempt to find and remove the key logger.
then basically you are up the creek without a paddle.

what is IDM ?
