Shutdown your computer when you do not need it
If your computer can be off out of hours, it means hackers can’t get into it. Hackers are most active out of your working/waking hours as that is when they can get away with things you are not likely to spot. Not everyone can leave their computer off out of hours and in these days of working from remote, it can inhibit you. Everyone’s situation is different. If you can shut it down, it’s a great habit to get into.
