Welcome to the new forums which only came back up today.
If the above has made matters worse then there has to be some strange malware in your machine, or it has done some damage.
I suggest you download Hijackthis and post a log on one of the following forums for expert advice.
Do not post the log here, we can't help!
Post the logs at a specialist Forum:
BLEEPING COMPUTER FORUM
GEEKS TO GO FORUM
MAJOR GEEKS FORUM
MALWARE REMOVAL FORUM
SPYWARE INFO FORUM
WHAT THE TECH FORUM
Be sure to read all the sticky announcements/instructions at the top of each malware forum!
