Everything I download I keep getting the "This file is damaged and cannot be opened, move to trash?" message and I don't know what to do anymore

The sudo-master disable command thing worked for a while but it's not anymore

This laptop isn't very useful if I can't download anything! Please help, after recovering from a kernal panic this is the last thing I need, I'm very frustrated with this 2017 macbook pro

I worry that this is a duplicate of https://www.daniweb.com/hardware-and-software/macos/threads/519467/i-m-so-sick-of-not-being-able-to-download-anything-on-my-macbook#post2250633 in which I note the error message may not be what you wrote.

Cross and duplicate posting for the same issue only adds more confusion. Why not update one or the other post and remove the duplicates?

By update I mean add the details here or there for all to see.

Checking the links as given they don't seem to be legitimate sources. Could be cracks or hacks. Apple is working hard to keep you safe.

Try what http://osxdaily.com/2010/12/13/open-7z-files-on-a-mac/ notes instead.

As to CCleaner, again another shady site. Why not get it direct from Piriform? I AM ASKING. PLEASE TELL US WHY THESE ODD SITES.
