Clean with Hydrogen Peroxide
Just put some 3% hydrogen peroxide into a spray bottle. Spray it on and wipe it off as you would with other household cleaners.
Hydrogen Peroxide is also great for removing blood stains, so keep a bottle in the laundry room.
Hydrogen peroxide is generally anti-bacterial and anti-viral, so it makes sense to use it as a household cleaner. However, it does take time to work, so the short amount of contact time in cleaning counters and windows probably won't kill all the tiny pathogens in your house. On the other hand, it's a step in that direction, and if you want to really sanitize something, you can leave the hydrogen peroxide for a longer time
