AdWare is the new evil

I spent all of last night trying to remove some AdWare that we managed to pick up on our computer. I'm still running Adaware, Spysweeper and CWShredder. I've rebooted five or six times and continue to get the adware replaced as soon as I reconnect to the net. I'm assuming there's one small piece that none of the software is finding that is running out and collecting all of it but I can't be certain (it could be some systemic vulnerability I suppose... )

I find it humourous that congress and the media are all upset over Spam when spam is nothing more then an annoyance. Adware is a vicious infection of your computer. Usually far worse then a virus because it infects your computer so pervasively that eliminating it is very very difficult (probably impossible without the help of dedicated software).

If anyone's got any suggestions on other software to try just let me know. If I can't purge everything this next time I try I'm going to throw another virus scanner on there and see if that isn't compounding the problem. God I love Windows XP and its security flaws.
