(Solved) Why didn't Avast Quick Scan

@DavidR,

MalwareBytes put this threat in Quarantine.

Registry Keys: 1
PUP.Optional.InstantSupport, HKU\S-1-5-21-2432266188-2506439190-3645350612-1001\SOFTWARE\InSTab, Quarantined, [7e57587bd1c81a1c2c9739947d86e21e],

Great - from your above post/s it looks like MBAM is detecting its own quarantine entry as seen as a registry PUP. Colour me confused.

I thought it put the PUP in quarantine.

I thought it put the PUP in quarantine.

From your images clearly not - it might be able to delete the registry entry, but it can't put it into quarantine as it isn't a file. Unless it is able to export the registry key (.reg file), but none of your images or info shows that.

But as I have said, what gets me is MBAM detecting a registry entry that is for its own quarantine area.

I ran 3 more MalwareBytes scans and each one showed 0 threats so this PUP should be gone now?

It is not a PUP, it is (was) a leftover reg key from a PUP

Yeah, a bit confusing. 

I suggest you install (if you've not got this already) this program:  https://unchecky.com/  By itself it should take care of the vast majority of PUP's you may encounter, including those you don't see, during install of another (usually free) program.

@mchain,

I have unchecky installed.  With the exception of installing the latest version of Avast I haven't installed any other program's.

Good to hear.  Also good to hear you've come to the point where you consider whether you need a certain program or not on your system, so that is also good.
