timmcat,
audiogalaxy was (is) a touch notorious because it gave the option of downloading 'gator'. Spyware indeed, in fact probably one of the cruddiest around. However audiogalaxy is a good app and if anyone wishes to use it go right ahead, just don't check the 'download gator' box when you install.
I downloaded 'adaware' some time ago (not sure on the link, run a yahoo search) and have been very pleased. It's freeware and it checks and deletes all spyware from any HD.
