Thanks @polyvertex for taking this into consideration and very sorry for extremely late reply!
I had v2.15.1 installed and now upgraded to v2.15.3 which works kind of expected, thus I wont have to ignore the Bookmarks package anymore.
Now keypirinha-2.15.3-x64-portable_2.7z and the file keypirinha.exe (in root directory) are showing red results on VirusTotal. Is that normal or should we be concerned?
It's a false positive (see #176), probably due to a heuristic algorithm being picky. Just ensure you download Keypirinha from its official website and check archive's SHA256 sum. See the "Checksums" file available on the Download page.
