But, as was pointed out, brightcloud.com (or webroot) really have nothing for which to apologise. It's all the fault of that damned "Automated Classifier" - that's who *should* be apologising.
FWIW, I imagine they're just running a signature based virusscanner, and those throw up false positives all the time (they're just scanning for byte strings)
But they should be running 30 virus/malware/scanners, if 10 or 20 flag the file, then it might be bad :) I don't think I've seen the same file flagged by more than 2 stay flagged for very long
