If it was not detected by other vendors, that never guarantees it was a FP. Maybe it was a zero day. Did you report it to Kaspersky or any other vendors?Speaking about K, it once detected Ulaa browser installer downloaded from Ulaa official website as a malware and reverted back the whole installation process.
Checked the installer by several reputable AVs; no detection.
One nice FP by K system watcher ruining my installation experience.
