Your computer was infected by unknown trojan. Pop Up?

I have this pop up that keeps on saying:

"Your computer was infected by unknown trojan.

It's dangerous for your system (critical files can be lost)!

Click OK to download the antispyware program to clean your system!

(Recommended)"

It happened so many times that I thought it was my Norton asking me to download this.....so i did. Bad idea!

I uninstalled the product that downloaded when i clicked the pop up.

Still, the message is coming up....i searched for the trojan, i turned off system restore...blah blah blah

Please.....Can someone help me fix this?!?

Who wait till you restore the computer! If the previos mentioned doesn't work then I would try some others before a system restore. Your computer is infected, But there is always more then one way to skin a cat. If www.spywaredoctor.com doesn't work try browsing around

Also I suggest making sure your antivirus software is updated and run a full system scan. Good Luck
