Install BOClean to remove trojans?

I’ve got BOClean installed on my own, clean system. I’m wondering, though, how it might respond if I installed it on an already infected system. Would it be effective in finding and removing any trojans that are already present? If so, how would I know when it had finished doing all it can by way of trojan removal?

Yes, cleaning an already infected system generally takes at the most a reboot to grab the last infectors. When BOC quits giving you prompts it’s through.
The first thing I do when working on a system is install BOC to watch my back.
