I once installed McAfee on a friend's computer, against my better judgement (he's a complete technophobe, had been sold it at some generic computer shop and been scared of installing it himself but sunk-investment and all that). McAfee said the machine was clean, although it was still showing some suspicious, if not definitive, signs of being infected. Uninstalled McAfee, installed AVG free, and AVG found six viruses. Six. One I'd heard of, and I've no particular interest in this kind of thing. That's as damning a verdict as I've ever seen, in my book. If I'd not have doubted McAfee, he'd have carried on with a false sense of security. McAfee is, and always has been, worse than nothing at all - at least with nothing at all, you know you're probably infected.
