Windows SmartScreen warning
Symptom: running vfxm-win.exe shows a blue
“Windows protected your PC” screen.
Cause: two things feed that screen — whether the file carries a signature from a publisher Windows can name, and how many people have already run that exact build.
From version 1.2.3 the installer, its uninstaller and reaper_virtue.dll are
code-signed and timestamped. So the first half is answered: the security
prompt names the publisher as Rodney Florencio da Costa, the name on the
certificate, instead of saying the publisher is unknown. Certum Code Signing
2021 CA issued it, and it runs until 19 December 2027.
The second half still has to be earned. It is a standard code-signing certificate, which carries no automatic reputation, and it is new — so SmartScreen’s score for it starts at zero and climbs with installs. Some people will keep meeting the blue screen for a few weeks after a release. Seeing it does not mean anything is wrong with the file.
Installers for 1.2.2 and earlier were never signed, so on those Windows has no publisher to name at all. If that is the download you have, the page below is still exactly right for you, and the checksum is the only thing that proves the file is ours.
The full click-through steps live on the Install on Windows page: click More info, check that the publisher reads Rodney Florencio da Costa, then click Run anyway.
If the warning doesn’t go away after reinstalling
Section titled “If the warning doesn’t go away after reinstalling”That’s expected — SmartScreen’s reputation score is per-file-version, not per-machine. Every new VFxM release has to accumulate its own runs, regardless of how many times you’ve installed a previous version. Now that builds are signed, the certificate accumulates a score of its own that later releases draw on, but it started at zero on 2026-09-17 and takes time to build.
Now that it is signed, has the warning stopped?
Section titled “Now that it is signed, has the warning stopped?”Not by itself. Signing changed one specific thing: the prompt names Rodney Florencio da Costa as the publisher rather than calling the publisher unknown, so you can see who built the file. Reputation is a separate score, and it is earned through download volume. Since March 2024 no class of certificate buys an instant pass, so a brand new build can still draw a caution screen for a while after it is signed.
