I already contacted Adobe Help/Chat and got a case No. 0220904483; the agent was Ajay Kumar. I explained my issue to him and he sent me a link to Adobe Forum where i would get help from experts.
Below, I am summarizing my issue once more:
I use a Mac and Google Chrome. On my Mac are 2 Adobe programs installed:
Repeatedly, after I get prompted to update my Adobe and do it, my Mac significantly slows down and is often blocked. When I upgrade Adobe, 2 malicious programs (see below) get downloaded into my Mac. When I ignore the prompt to update Adobe, I cannot shut down my Mac - the system reports that Adobe prevented the Mac from shutting down. I learned to go to my hard disk, into Library, under LaunchDaemons and check for malicious programs. Everytime, following 2 programs are there:
When I delete these 2 programs, the problem is solved. Until the next time I am prompted to update Adobe.
