I didn't think modern A/V products included complete historical sets of signatures. I'm sure they can deal with ancient, simple bootloader infections and such, but at some point I'd be concerned there's a gap where something might be too new to be detected by the simplest heuristics, but too old for a more sophisticated signature to be in your common modern products. But this isn't something I've had to deal with. Is this an imagined problem, or has somebody run into this? Thx, --S.
