What do I do to permanently remove 180Solutions.Zango?

I always do daily antispy scans but Windows Defender BETA, Ad-Aware, and Spybot-Search and Destroy never EVER detect 180Solutions.Zango, but Yahoo! Antispy does. I really hate it and I really want to get rid of it and make it stop bugging my computer so much. What should I do to permanently remove this annoying piece of Adware, once and for all?
I don’t know why my computer keeps on being infected with 180Solutions.Zango, and I don’t have anything that was made by Zango at all. Just telling me to remove it from Add and Remove Programs will not help.
