It would seem the Sony rootkit case is mostly over, at least for now. Several people probably learned valuable lessons over the last two weeks.
There's a nice wrap-up at The Inquirer. We especially liked this quote:
But enough ranting. Let me end this with a couple of up notes. If you want to find a trustworthy security vendor, I would recommend looking for ones that stood up on the Sony malware DRM infection issue and said 'this is bad' early and loudly. F-Secure comes to mind, but there are others. The ones that said 'grumble, mumble, maybe, sorta' a week later are not what you want to have protecting your machines.
