About plasmatic
We make ZeroDay, a free antivirus for Windows.
Why ZeroDay is free
Most free antivirus pays for itself with bundled software, upgrade nags or your data. We didn’t want to make that.
So ZeroDay has no ads and no paid version, and we don’t sell your data.
How we handle data
As little as possible. ZeroDay checks hashes, not files. This site has no tracking at all.
