Re: Spyware/malware programs
I don't know much about Yahoo messenger and I don't see how you think it's spyware causing multiple logins. Sounds like someone may have hacked your account. I would do the following:
* Change your password.
* Try a multi-IM client like Pidgin and see if it keeps kicking you out.
* If those don't work, contact Yahoo support and see what they can do to help you.
* If all of the above don't work, go to a different IM provider like Google Talk or MSN.
