When I install Creative Cloud app I get the Search Mine malware. This has happened mutiple time on my iMac requiring me to go through the process of removing the malware. This morning I removed Creative Cloud and downloaded a new install from Adobe.com. Immediately I have Search Mine malware installed.
This has nothing to do with Adobe. This is a browser hijacking issue unrelated to Creative Cloud. It sounds like your computer was infected long before now with a persistent malware. SearchMine re-infects your Mac multiple times unless you delete all of its fragments, including hidden ones.
