Protection that feels modern, not magical
Big antivirus companies love black boxes and fear marketing.
Stellar does the boring part: clean UX, clear signals and
privacy-respecting defaults.

Questions people ask before buying security
Skepticism is healthy. Here is what we do and do not do.
Is Stellar Antivirus really open-source?
How many devices are included?
One license works for up to 8 devices across Windows, macOS and Android.
Does Stellar Antivirus upload my files?
By default, scanning runs locally. Diagnostics can be enabled by you and the app should clearly show what is shared and why.
Will this slow down my device?
The goal is low overhead, smart scanning and sane defaults. Real-time protection should be efficient and scans prioritize responsiveness.
What platforms are supported?
Windows, macOS & Android.
Stop trusting black boxes with your security.
Stellar Antivirus is built to be fast, understandable and verifiable. If you care about privacy, this is where you stop settling.
