why does chrome say this download is a maleware ???
Lemme guess...you took Mixdrop as Host...
Take the link and post it on Virustotal, you'll see that pretty much non of the abundance of anti virus tools see anything wrong with it, but some "Cybersecurity" companies from Vietnam and co still do for some reason...
Mixdrop, atleast for a time, was used to spread malware, and for that reason now, many browsers just assume that it still is and flag the files regardless.
But if that were true, i would be more virus than anything else by now, neither MWB, nor Kaspersky nor Windows Defender found anything...
