I am too stupid to help you but I curse the first person who asks you if you are logged in.
go to www.avast.com and download the free version (personal use)
It is the best one I know of.
Please don't waste your money paying for either one of them there is so much good anti spyware stuff available for free.A combination of the following will do a fine job of keeping your computer spyware free;Spybot Search an Destroy,Spyware Blaster,Adaware, even Micrsofts anti spyware beta works great if you have XP and is free as well.Just do some google search's for the above mentioned, download,install and your in buisiness.Yahoo toolbar also has a spyware removal tool but so far it hasn't found anything the others didn't already catch.You can also clean your registry with CCleaner, also free, and it will help keep these things from comming back.
I'd say the problem is more that you're an incomplete computer nerd.
Spybot search and destroy, Adware 1.0 personal and SpySubtract Spy Trap. All are free I use them all and install Fire Fox 1.6 , it even kills pop ups on Drudge, the dirtiest site on the internet.
Save yourself a lot of headaches and money. Buy a MAC.
