This file is extremely suspicious.

Indeed It Is.

Perhaps It was unbeknownst to the OP so for the moment, I've removed the link.
Appreciate the In depth analysis.

Perhaps.

The thing is the file literally does nothing else but download the file and run it in the background with no window; etc.
unless OP blindly reposted something he never tested to see if it worked as intended.
