- Make sure your firewall is turned on. It's the first line of defense against viruses and malware
- Turn off settings like 'network discovery' and file sharing' -- that will make it more difficult for people near you to see your data
- Set up automatic updates on your devices -- and always install them when they're offered to you
- Consider using a virtual private network, or V-P-N.
Every adjustment can make a difference, according to Consumer Reports.
