Yeah, I also do repairs, and heard someone mention it, but was kinda like ok, don't know about that. But then my wife read a computer shop's facebook page that said they came across it. Just seems serious if it's real. Didn't know if anybody here had heard of it or seen it yet. The newest viruses out there seem particularly nasty.
As far as AV, I've worked on systems with updated AV, and still they've had nasty rootkits before.
