Hello,
I understand that its a false positive but end-users don't and we've received thousands of inquiries about this issue in the last few days
I am deeply sorry about this inconvenience - I really can understand how frustrating this is considering we've encountered this in the past as well.
Why is the base stub from Advanced Installer getting flagged for those in 21.9 while it wasn't in 19.x
The only reasoning I could find is that the ones from 19.0 are much older and therefore "trustable", while the ones from 21.9 are new. This is not the first time this has happened, unfortunately and that's the only logical conclusion I could draw from that.
Although nothing much changes between different versions, sometimes the resource gets flagged. For instance, in our case right here, it is the updater which has been the same for years - no major code changes at all.
I'd really do something to help here, but I'm afraid it's out of my reach - as previously mentioned, we do this for our product already. Before each release, we scan every binary from Advanced Installer + the MSI installer and submit for whitelisting if any major vendor flags us (e.g. BitDefender, Karspersky, ESET, etc.).
Thank you for your understanding!
Best regards,
Catalin
