I already have McAfee. Spybot is good and free. Adaware is supposed to be good also. But, at the Lavasoft site, you have to buy a subscription, whereas it used to be free (at least a free trial). There are several
other places that claim to have a free adaware download, but I suspect they are fakes.
BTW Arnoldclone, the wife is out of town, so I have to look at porn.
