Windows xp security centre bug?

I had a pop-up saying that my pc was infected with spyware, trojans etc and that i must download 'Windows XP Security Center'. So I did!!! I now have a professional looking program asking me to enter my email address and password in order to run program. Please can someone help me to remove this! Should I download HijackThis as a start? Thanks

Download, install and run HJT

Download HJTInstall.exe to your Desktop.

• Doubleclick HJTInstall.exe to install it.

• Click on Install.
• It will create a HijackThis icon on the desktop.
• Once installed, it will launch Hijackthis.
• Click on the Do a system scan and save a logfile button. It will scan and the log should open in notepad.
