So who is this? Possible virus and miner hijack, attempting to look legit with a 'fix' to get people to download these files. What fix? Why is it needed? Considering reporting to a moderator.

That user is a "bot" or a "farmer". He's just copying old posts and pasting them like they're his own. His post above in this thread is probably SP's post from ~ 2015. How else would those poor idiots farm their bitcointalk accounts? When they post useless crap like "interesting project!", "good job!" etc, they get reported for low quality posts. So they figured they'd just copy some old valid posts from other users and paste them as their own thoughts. Except they're so stupid they can't even pick the right posts to go unnoticed. This particular guy managed to post links in this thread, and he also copied someone else's post in another thread saying how there's going to be reward halving for LTC in a couple months and how LTC is supposed to cost at least $8 if BTC is no less than $230.
