Yep, you definately did get the wrong Forum...
but use GOOGLE and search for AVG or AntiVir, both are good AntiVirus programms which offer a free version...
but you mentioned Norton, as having caught the critter, what is up with that? if the version you have is not updateable then you will certainly need to DeInstall it first before you install another AntiVirus proggy...
Download the following aswell, they are Anti Spy- and Adware programms that will take care of quite a few pests themselves that AntiVirus will not touch...
AdAware from Lavasoft, SpyBot S&D, and Microsoft AntiSpyware programs...
good hunting...
