I reported the "false positive" to the Vipre people and gave them the download link to obtain it directly.
Vipre is reporting "Trojan.GenericKD.33560416" <<-- Vipre considers that a malware indication.
Usually Portable Apps stuff does not trigger any AV warnings for me.
I will say this about what I saw tonight: When I checked for updates about 4 hours ago, this file refused to download. The Portable Apps Updater "errored out". Now when I ran the Updater I got the updated ConvertAll installer, but running the installer triggered my AV, quarantined the installer, and broke the installation process.
