Great job as usual avast >:(
And that is CCleaner i assume?
Yes, it sure is CCleaner straight from the Pirifom website.
Can you submit this file?
No as it seems to be a temp file created during the installation of CCleaner.
I have ccleaner 5.33.6162 installed on both my winXP and win10 systems and no alerts when I was installing it. I downloaded this version on 17/8/2017,
I hadn’t installed this update on the win7 system previously (as I don’t use it very often. I did install it on my Win7 system just to see if it wasn’t virus signature thing and did a context menu scan on the ccsetup533.exe file. I then installing it over the top, it has just completed and nothing found in installation.
EDIT; added screenshot from win7 installation.
