Very old news.

Your report is dated September 2017.

Perhaps you had CCleaner 5.33 installed. Make sure you are using latest CCleaner build 5.40

These seem harmless but I remember a while back that someone hid some malicious links like that.

No offense meant to inteltek2, just wondering.

Actually even the installer file will trigger this. The compromised version 5.33 of CCleaner does not need to be installed.
