I pick McAfee instead of Norton/Symantec if I had to choose a pre-installed antivirus which come pre-installed in pre-built computers from PCs like HP, Dell, Asus, Lenovo, and Acer. I used McAfee at school and home computers, and McAfee works good enough on computers which have McAfee installed on them. McAfee is not my favorite choice in antivirus, but I feel safer using McAfee than Norton and Windows Defender. McAfee LiveSafe has 4.5 stars out of 5 stars from Amazon.com users on https://www.amazon.com/McAfee-LiveS...id=1512684652&sr=8-2&keywords=mcafee+livesafe McAfee license works on an unlimited amount of devices. Symantec Norton has 4 stars out of 5 stars from Amazon.com users on https://www.amazon.com/Symantec-Nor...d=1512684699&sr=1-4&keywords=norton+antivirus Norton also has a higher percentage of low Amazon star reviews where users gave it 1 or 2 stars out of 5 compared to McAfee which have fewer low reviews. The low rated reviews also seem more serious for Norton like "Do not buy this software, you will never get rid of it and be charged automatically for YEARS by this company" But, Norton license can only be used on 1 PC. Norton also does not have many bad news stories. I read an articles which complain abuot Norton like Security vulnerabilities in Symantec and Norton 'as bad as it gets' warns researcher which says Norton and Symantec Antivirus contains a very bad security vulnerability which makes Windows very insecure, and the Norton/Symantec user on the PC does not need to interact with the computer to get it infected. There are also many forum posts on Norton's forum like norton broke my computer windows 10 | Norton Community where Norton software broke the users Windows 10 install, and other software. "I was upgrading to Norton premium and from that moment on after the restart I just get a series of blue screens, the damage is so bad that I cannot even open in safe mode." Tech reviewers like Leo Laporte don't recommend Norton products because it is bad to use. He got very mad with Norton antivirus where he stomped on the Norton box, and kicked the box in the video I posted below.
