You may want to try these three things. . .
1. Download Spybot Search and Destroy(it's free and you can get it at download.com, it works wonders)
2. Also download and run Adaware (you can get it from lavasoft.com, it too is free)
3. Finally download a program called hijack this and go to a website called techguy.org. It is a forum, so you have to register and then look into how to run hijack this. The guys over there are super friendly and will give you a step by step for running and removing things on hijack this because this program is pretty serious and if you remove the wrong thing you can mess up your computer.
Also what antivirus are you running cause you could have a virus?
