Why didn't Avast Quick Scan find this PUP
would be easier if you did not post half the question in the topic title and other half in the post, but the hole question in the post

Anyway, probably because it is in a location where quick scan does not scan ... seems to be just a registry key / leftover

Quickscan = quick because it does not scan the hole computer   ;)

It is fairly obvious the detection is not a file but a Registry Key.
- PUP or not a registry key without the associated file is inert.

What we can't see is the complete text of the location in your image as it appears to be missing what the software is or any file name.

Still cant see the complete path, a screen shot from within the Quarantine would be much better.

avast has probably blocked or removed it some time, when you scanned now avast detected the leftover registry key

Run a scan with Malwarebytes just to be sure the crap is gone

That is what I thought, essentially an empty/inert registry entry, without an associated file. Not to mention that this is pointing at some sort of Quarantine location - for InSTab - I have absolutely no idea what this if for or what program this is associated with.

But there are indications it (InstantSupport) could be malware related - http://www.bleepingcomputer.com/virus-removal/remove-instant-support.

The reg key looks to be from a MBAM scan as Avast does not register reg keys just files

Yes - that is why -midnight was asking, why didn't avast detect this.

But broken over the topic Subject and a continuation of that line in the post.
