You probably caught this infection by attempting to watch a video at some website. The site said you "needed" a codec or a phony Active-X control so then you downloaded it to watch the video. This was actually a ruse. A scam if you will. It was not a codec at all. (The video would have played fine without that "Codec")! What you actually downloaded was a Trojan called "Zlob".

This trojan then "phoned home" and installed the popup saying "system alert" adware on your computer with out your knowledge.

Your computer has a Smitfraud infection now, which is a very difficult one to remove. Most "all-purpose" anti-virus and anti-spyware programs (such as have been recommended to you) can only remove the original Trojan Zlob which caused the infection and not the infection itself.
