Did you just upgrade your Windows (e.g. to Windows 10 version 1703)?
Usually after Windows upgrade, SecureAPlus will switch to Observation mode while re-whitelisting Windows files, otherwise there will be a lot of new files get blocked. After re-whitelist Windows files, it will automatically switch back to the normal mode.
During Windows upgrade, there was a period of time where SecureAPlus can't keep track of the new files installed by Windows. This is because there was a time when Windows restart in its own exclusive mode to install the new files without loading any driver or application.
If you encounter a lot of prompting due to a lot of untrusted new Windows files, we will recommend you to uninstall and reinstall SecureAPlus. This will allow SecureAPlus to re-whitelist your system.
