Many people simply don’t understand what a PUP is, even less what that particular detection might be, e.g. what the hell the file is or does and if it is legitimately on their system.
So a huge majority of your average Joe users aren’t equipped to make the decision about PUP detections and would generally delete them (or rather allow avast to send to the chest, if that is the default detection).
You only need to browse the viruses and worms forum to see this in action, so avast have aired on the side of not having the user confused and making a bad decision. Whilst that is OK for most average users (not wanting to be constantly bombarded with decisions to make), it can reduce the detection rate on some tests like this.
