A friend recently and unwittingly downloaded and installed the iminent toolbar, etc. It has taken over his whole machine. We are in the process of removing it.

He runs a recent version of the free Zonealarm firewall. It didn't detect iminent at all at the time he opened the installer.

I am running ZA Extreme Would that have caught it?

Can Zonealarm not detect malware installers piggybacking on other installers or is iminent different in some way? It doesn't appear in the few malware databases I have checked.

Anyone have any insight? Thanks.
