MyWot is almost entirely the opinion of users, not (malware) experts and guess why so many systems get infected...
It is because the majority of users have no clue about security.
It is not weird at all that Asyn (as well as me and many others) say not to download from Softpedia.
Fact is that when they started it was a good and trustful site to download from.
Over time they allowed more and more software that at least could be considered as a PUP.
And if not for the software itself, the installers often install (or at least is trying to) install PUP's and/or worse.
Softpedia is not checking that.
A real simple thing they could do is checking if the installer has the same hash as the one on the official (developers) download site.
