Hello and welcome to Bleeping Computer. Your problem
is a common one and pretty simple to fix. You have a
couple of options, really. You could grab that link in my
signature below (the HijackThis link) if you don't have the
program already. I strongly suggest you get it. It's the first
step in fighting hijacks and spyware attacks, etc... Refer to
the link for the information and the download. Once you have
the log ready, please post it in the HijackThis Logs and Analysis
forum. Our staff of experts will view the log and let you know
what needs to be done. Please make no attempt to make any
changes yourself. It's vital that only experts guide you on what
If you choose not to take that step, please get the HijackThis
program nonetheless. It's my first suggestion.
Your other option is to do a System Restore. Think back to when
this problem began and choose a system restore date on the
calendar accordingly. Just keep in mind that if you have done
any downloads or installations of any kind will have to be redone.
If you choose this method, download and install HijackThis afterwards
so you won't have to redo it.

XP, please click here
Let me know if either or both of these helped you. Good luck.
