How to remove virus Program "vista smart security"

A virus warning popped up and started to scan my computer, then it wanted me to download an update.  I looked around on the web... I'm sure it's a "fake" warning, and I am getting conflicting information from anti-virus software sites on how to remove it.  As far as I can tell, it's a "false virus program" (a Trojan, perhaps?) that encourages you to download stuff off other sites.   I tried removing it with "Super Anti Spyware" without luck.  I checked the EE knowledge base for "Vista smart security"  and couldn't find any info on how to remove it.  Has anyone dealt with this or can you direct me to a legitimate removal protocol? I can send screen shots of whatever you need.

bryon44035v3 read my mind. after that, use microsoft security essentials. I know its microsoft but this program has surpised me quite a few times.
Go with crzyivan0000 and MSS.

But I will note that based on your question, you might not have installed the virus but only been subjected to it's web based come-on. If that's the case, you are safe, though you might want to reconsider visiting the websites that had the fake AV program as ads...
