Having worked that "mystery virus" topic before being carted away on medical leave, I can confirm that was not the average run-of-the-mill malware. From what I've seen here and elsewhere in other malware forums, the criminal effort is definitely seeing malware as a very cost effective method, and they're getting good at it. And not just the classic PC malware, but the atypical and unexpected, as pointed out with the BIOS. There are also MBR attacks, as described

Since there doesn't seem to be a current malware problem to be worked in this forum, I'm going to close this topic.
