Could well be they are not listed (t)here, because Avast detects these only when in PUP-mode.
Did you scan with Avast and PUP-mode enabled?
This distinction should be made by common users to not miss detection for potential unwanted programs.
Quite some users with residential Avast-AV also have MBAM installed just for such additional detections.
PUP.Optional.BundleInstaller.A is just an example here.
Also the IPs should be alerted, like https://cymon.io/23.62.236.153 in the case of http://webcache.googleusercontent.com/search?q=cache:1Q73hW7fpqQJ:urlquery.net/report.php%3Fid%3D1441920346652+&cd=1&hl=nl&ct=clnk&gl=pl

P.S.

Malware more often changed themselves. perpetrators changes the code with little variance and redistribute… Even new malware are generated day by day … There are no boundaries or limitation for modern malwares and virus… There are no perfect antivirus solutions… each and every antivirus/malware solution is having its own limitations and possible loopholes
