"Spamkiller"

Does anyone use this program....spamkiller...???

http://www.spamkiller.com/

I have been getting almost daily email for this address: yougofirst@ivbs.com. Each day it will have a different persons name...Ken, Brenda, George...and a place to unsubscribe. When I "unsubscribe" it tells me that it will take a day or two to take me off the list...and I never get one from the same name twice.

When I search for YouGoFirst a web page of some singer named Andrews comes up...not connected to this yougofirst at all....as for the ivbs.com...I get nothing in google. I called my IPS and a tech told me to download this program. Any feedback on it?

Thanks! Jo

P.S. All the mail comes in my husbands name....which is strange as he never did anything but downloaded stuff and changed settings on this computer...his name only appeared through dealing with the Online Support with Sears!!
