Is a downloaded installation file a fake spyware of special services ?

I went to https://www.ccleaner.com/ using the latest version of official Chrome browser.

The download process has started. I looked at the download link. There it is:

https://bits.avcdn.net/productfamily_CCLEANER/insttype_FREE/platform_WIN_PIR/installertype_ONLINE/build_RELEASE

It's normal? Official site?

I am concerned about the safety of downloading this file, because the special services of my state made attempts (there are articles in the news about this) to interfere with the work of this program.

  I know that they can forge a certificate that validates the authenticity of a file received over the Internet. They have already been caught on this.

See my screenshot below I have just done for you so you could see what I see when I download. (I did the free version )

avcdn is an abbreviation for Avast Content Distribution Network

Avast own Cleaner.
