I got a pop-up to inform me there was a new free version available. After I upgraded it, it scanned my pc. My Windows antivirus got disabled somewhere along the line. I tried to activate it and got error messages. I then updated the antivirus and decided to do a restart. My Windows did not want to open. Having tried a few times, even via Ubuntu where I got an onscreen message to inform me that Windows cannot start without its start-up disc. Oh no, this is bad!
