Download Ad-Aware 6.0 from Lavasoft (it's free) and run a scan and delete the garbage. A lot of the ad/spyware puts itself in your registry so even if you delete it from your desktop it'll reappear the next time you go online. And forget about manually deleting it from the reg. edit. . . . you'll be there all night and you'll end up getting most of it back again since it's getting through your firewall. Ad-Aware will prevent much of it from getting back in, though you'll still want to run a scan every week or so.
