assume all downloads legal
LBRY claims to tell you the correct file type before you download a file (let's assume that it's impossible to include a second file). I'm aware that downloading executable files could be dangerous but I've been told that video files (.mp4 etc but apparently not .wmd) are safe as they can't contain anything in them except malware.
LBRY is similar to Torrent so I've researched from that perspective. The general consensus is that if it comes from a trusted source and has lots of seeders it is GENERALLY safe. First of all that's not good enough for me, I know the internet is risky on its own but I don't want additional security risk. Second, just because a lot of people download from the host and think it's safe doesn't mean that there isn't something malicious that still hasn't been uncovered by anti-virus software (would probably require the abilities of a state-sponsored hacking team).
I'm really interested in playing with LBRY but I'm just not sure I can trust running it on my Mac. Kazaa destroyed my old computer (back in the day) so I've never experimented with P2P again. This mac runs perfectly, I want to keep it that way.
I'm running latest Mac OS.
Current theory is that it is unsafe unless I run a sandbox within a Linux VM but that sounds like a hassle to me...
