A notification randomly appeared while I was using my computer at the bottom right of the screen informing me 'Drivers had been successfully installed' and the Internet connection disconnected suddenly. I didn't install anything.
Should I be concerned and what can I do to investigate this? I've scanned my computer using Avast and I have checked the list of installed drivers but I'm not sure if the date displayed is the actual date they were installed/updated. Any more suggestions? What could have caused this?
