Found this and wondering if other users have tried this as an On-Demand Scanner, and if so, has it a good Detection Rate? Also, thought some users might want to test this out, and, if any users do, I'd be interested to know what their thoughts are on it. I haven't go round to testing it out yet, so I don't know if this is compatible with Norton.
