...as long as you know what you're downloading. BlackICE has trojan signatures in its database, but it's just like most crappy virus software- it looks like they have to add new variants to that database before it can find them.
I've had BlackICE Defender catch the SubSeven trojan on my parents' computer upstairs, and it did catch the outgoing packets. I admit I have no idea if it actually blocked them or not, but it did see them...
Of course, I happen to like BlackICE Defender, and Steve maintains that it's complete shit. I just think ZoneAlarm is a tad annoying after asking you if you want the first 40 programs to use your network adapter... and not allowing anyone to ping you... (You'd think this wonderful program would have a better way to block 'ping of death', 'smurf', and other attacks than simply blocking ALL pings.)
But then again, I rarely download executable attachments. For the average user, I'd say ZoneAlarm would probably be a better idea- IF you can convince the user to not click 'allow' every time a damn program tries to use the network (which is the fatal flaw in the program).
On a closing note- I hate the way Steve writes some articles, especially the security ones... There's too much sensationalism. He could write for a tabloid. The facts are there; I just don't like how he presents them. I suppose he's just trying to make them easy for the average Joe to understand, though.
