McAfee’s 2018 Windows antivirus lineup can cover all the devices of a large family. All of the company’s products come with a file shredder, many have an excellent password manager, and the top end offers backup software. Many of the products can be installed on up to 10, and perhaps more, devices using a single license.
On the downside, McAfee’s antivirus software won’t let you opt out of system-data collection, and it uses an excessive amount of system resources.
