Which one is for you
Pick Avast if
- Fits if you want real-time antivirus on a Windows PC and don't want to pay
- Works for families mixing Windows, Mac and phones, up to 10 devices
Look elsewhere if
- Skip it if you want one price for everything, as the VPN and Cleanup are separate subscriptions
- Not for you if auto-renewal bothers you, as paid plans renew by themselves and some trials want a card
- Pricey if you keep it past year one: 10 devices go from $69.48 to $99.99, and one computer from $49.08 to $77.99
- Watch out: first-year prices are for new customers only, and Ultimate renews at $109.99 for one computer
- Tight if you want Bank Mode, Email Guard or webcam blocking free, as they're Premium only; there's no web app
Pick K7 Security if
- Fits if you want a home antivirus that also has an iPhone app
- Works for people who want a lifetime licence option, as the site advertises Infiniti for up to 5 devices
Look elsewhere if
- Not for you if you want a price you can check: the storefront loads prices by script
- Skip it if you use a Mac, since none is listed
- Watch out: the $11.11 offer is for 2-year purchases only and renewal terms are not shown
- Too light for detail: the listing records only the home page
How we grade them
| 3.0GPAAvastVery good | 2.2GPAK7 SecurityFair | |
|---|---|---|
| Value for money | CFive devices means the 10-device plan, $69.48 the first year and $99.99 after, so two years cost $169.47, about $7.06 a month. That's above the dearer quarter of antivirus but short of the dearest tenth. One computer is $49.08, then $77.99. | CNo plan price could be read, so it sits at the ordinary grade. The banner offer of $11.11 for 2 years is a promotion with unknown renewal terms. |
| Free plan and trial | AAvast Free Antivirus gives real-time file, behavior and web shields, ransomware protection, a firewall and network scans, and there are free apps for Mac, Android and iPhone too. Bank Mode, Email Guard and webcam blocking need Premium. | DA Free Trial link is in the site menu but no terms are recorded, so it earns a D. |
| Features | BReal-time shields, ransomware protection and a firewall even when free, then Bank Mode, Email Guard, Deepfake Guard, a sandbox and webcam blocking on Premium. Nothing in the listing shows a gap in the core protection. | CHome antivirus suites for Windows, plus business endpoint security, but the listing records no feature list. |
| Ease of use | BNo store rating on record. You install it and the shields start, and everything sits in the one Avast One app. | BNo store rating on record, but it is a consumer antivirus you install and run. |
| Platforms and integrations | BWindows, Mac, Android, iPhone and a browser extension, with Multi-Device covering up to 10. No web app or API on record, so it stops at B. | BWindows, Android and iPhone are listed, with no Mac and no integrations. |
| Best for | real-time antivirus without paying | Windows, Android and iPhone home antivirus |

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.
