Head to head
Avast vs AVG: Two Interfaces, One Engine
Avast and AVG are owned by the same company and share the same detection engine. Any comparison claiming a large gap in protection between them should be treated with suspicion. The real differences are interface, bundled extras and how each free tier is packaged.
Comparison table
| Detection engine | Shared Gen Digital engine | Shared Gen Digital engine |
|---|---|---|
| Free Windows tier | Yes, with File, Web and Email Shields | Yes, with file, web and email protection |
| Interface | Denser, more modules visible | Simpler and more traditional |
| Wi-Fi scanning | Wi-Fi Inspector in free tier | Network scan available |
| Free Android app | Yes | Yes |
| Free Mac app | Yes | Yes |
| Optimisation tools | Avast Cleanup (separate) | AVG TuneUp / AVG Cleaner (separate) |
| Best for | Users who want more visible modules | Users who want a simpler screen |
Do they detect differently?
Not meaningfully. Independent test results for the two brands track each other closely because they run the same engine and the same cloud infrastructure. Choose on interface preference, not on a supposed detection gap.
The privacy footnote
Both brands sit under Gen Digital, and Avast previously faced scrutiny over browsing-data monetisation through a subsidiary that has since been closed. Whichever you install, read the data-sharing options presented during setup rather than clicking through them.
Verdict
Install AVG if you want the simpler window, Avast if you want more visible controls. Functionally you are choosing a skin. If neither appeals, Bitdefender Free or Microsoft Defender are quieter free alternatives.
