Okay, but what about this one (Trojan Downloader Keenval.K)?

I've looked at the Symantec site and at Grisoft (AVG) and even at McAfee but not one of them has a stitch of info about it. Well, I'm about to check back just now but thought I check here first, and here you folks are talking about Trojans. So, I thought I'd throw this one into the mix to see what you might dig up.

I thought I was protected from this sort of nonsense. Does this mean I'm not?
