About five weeks ago Symantec messes up their AV signatures and accidentally classified some Windows system files as viruses. The files were only part of the Simplified Chinese version of the OS, so presumably this didn't get as much testing as a regular configuration.
Yesterday it was announced that they would compensate those folks who got hammered with some compensation.
I'm going to be very interested to see how this plays out, whether the lawsuits move forward, etc. This is a pretty clear example of harm done by Symantec, and certainly not intended behavior. Not clear whether this falls into the "didn't test enough" category of mistakes or what. Perhaps they bypassed their internal processes to release these signatures? Either way I bet they are hoping they have a good audit trail internally to show exactly how/why this happened.
I'll be watching this one to see whether any of these folks persist in their lawsuits and whether this ends up making any case law about software liability.
