Link 2,4-5 are showing a different Sha256 than the correct one. Link 3 this time came back as a match. Tested them all again on FireFox v(63.0.3).
So internet is being funny I guess.
I tried all four downloads on both Chrome and FireFox. Using Raymond Lin's MD5 & Checksum Utility 2.1, The result was the same each time. Checksums are not matching.
The File is compromised and has been infected if I had to guess.
File downloaded is showing different Sha256 checksums.
Correct Sha256: b008cc17cf80f5faf8d9661cf168809f562b7842449352bd5c9f3976925744c9
