Which one is for you
Pick Comodo Internet Security if
- Fits if you want a free antivirus and firewall on a Windows PC
- Works for a home user who wants a sandbox for unknown files
Look elsewhere if
- Skip it if you use a Mac, phone or Linux, as it's Windows only
- Watch out: the pages list Windows 10, 8 and 7 and look dated, so check current support before buying
- Watch out: the homepage leads with website and enterprise products, with consumer security further down
- Watch out: the virus-free guarantee covers up to $500 in repair costs for US customers only
Pick Malwarebytes if
- Fits if a computer is already acting up and you want a free scan to clean it
- Works for households of up to 10 devices on one family plan
Look elsewhere if
- Pricey if you have four or five devices, since that means the $119.99 family plan
- Skip it if you want the free version to stop threats, as it has no real-time, ransomware or phishing protection
- Not for you if you're on a Mac and want the firewall control, exploit protection and webcam monitoring Windows gets
- Watch out: Ultimate is $139.99 the first year, then $279.99, and plans bought online renew by themselves
- Too light for small businesses, as home plans are for personal use and Teams is sold separately

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
