In some cases, Panda even requested a reboot to complete its hari kari.
Systems that were not rebooted were unusable while Panda held everything up.
Of course, Panda later released a tool to fix that if you rebooted your system. But it only really works if you can boot into, at a minimum, safe mode. But I still find it very hard to believe that if they were testing these updates that this would have happened. I have a feeling a chain of technicians got complacent about this, and a string of managerial staff is probably going to get fired as a result. I know they're not the only company to screw up an update like this, but this really is quite nonsensical.
