Dear Pondus, winrar.it is the official partner of rarlab.com or better than "win.rar GmbH" then Alexander L. Roshal creator of Winrar.
So I know what I say.
You can see that I have not only written PUP but also win32: dropper-gen.
So if Avast detects a false malware and slams him in his trash Avast breaking my balls.
Finally, remember that Virustotal is not the solution to all ills and that proactive and heuristics detections made by other anti-virus engines can fail in the assessment as much as Avast.
Thanks.
