Which one is for you
Pick Bitdefender if
- Fits if you're on Windows and want real-time antivirus without paying
- Works for families with lots of devices, as family plans cover up to 25
Look elsewhere if
- Pricey if you pay yearly, as Total Security jumps from $59.99 to $109.99 at renewal and every plan renews at full price
- Skip it if you want a full VPN on Antivirus Plus or Total Security, which cap it at 200 MB a day per device
- Not for you if you want free protection on a Mac or phone, as the free version is Windows only
- Watch out: identity insurance and credit monitoring sit on Ultimate Security Plus, $189.99 a year after a $119.99 first year
- Tight if you'd rather not make an account, as even the free antivirus needs a Bitdefender Central sign-up
Pick Certo AntiSpy if
- Fits if you suspect a stalkerware app on your phone
- Works for people who want a check done on iPhone or Android only
Look elsewhere if
- Pricey if you want Premium Plus with the VPN, at $84.99 a year
- Skip it if you want protection for a computer, as it covers phones only
- Watch out: the deep spyware scan on iPhone needs a computer
- Watch out: Android prices differ from the App Store figures recorded
- Tight if you stay on the free tier, which does less on iPhone than on Android

|---|---|---|
| Value for money | CTotal Security covers 5 devices for $119.99 for the first 2 years, about $5 a month, right at the dearer quarter of antivirus.

| Free plan and trial | BAntivirus Free gives a Windows PC real-time malware and ransomware protection with no time limit, and one person on Windows could live on that. Macs and phones need a paid plan, which you can try free for 30 days. | CA free tier with a vulnerability scan and health check on iPhone, and spyware detection on Android, plus a 7-day trial of the paid plans. |
| Features | BAntivirus and scam protection on all four platforms, a password manager from Total Security, parental controls on family plans and identity monitoring higher up. The VPN is capped at 200 MB a day below Premium Security, but the core protection has no gap. | CSpyware detection and privacy checks. It does that one job on phones and covers no computers; the deep iPhone scan needs a computer. |
| Ease of use | B4.68 from about 38,000 App Store ratings, a whisker under the 4.7 an A needs. Even the free version wants a Bitdefender Central account first. | BNo store rating on record, but it is an app you install and run with little setup. |
| Platforms and integrations | BWindows, Mac, Android and iPhone, with family plans stretching to 25 devices. No web app, integration list or API on record, so it stops at B. | CiPhone, iPad and Android only. No Windows or Mac apps. |

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.
