Tartube Malware???

Ok so I grabbed the portable version from Sourceforge to pirate a few of my favorite channels from YT and after a few minutes of working, Malwarebytes Pro coughs up a furball and tells me one of the files is infected with a Generic.Ransomeware???

Anyone else ever run across or hear of anything like this? I know false positives are rampant these days but I'd rather not take the chance.

Also, not to sound stupid but is Sourceforge not the original place to get Tartube???

Thanks for any constructive input!
