So yes I sent you to the official download, that will make you download "construct2-r190-setup.exe" if you take it directly from the website, and should allow you to download the same file even if you take it from torrent.
Nowhere is there a trace of "systemprotector.lua" in that installation file.
It's likely you got your computer infected with it from elsewhere, and it is a file/software (apparently with a quick google search the software "Advanced System Protector" that can be erased with CC cleaner).
Before raising hell every now and then, you should first have a look around and search by yourself before throwing accusations.
Also, people who are still using r178 generally tend to be using an old pirate license.
It did not really occurred to me in the previous topic and I still went right away to provide help.
But if it ends in allegations that "a moderator is framing you" perhaps your next request for any kind of help will simply get ignored.
