Thanks Sheena for your reply,
but I've already tried this link and in the latest post it says to start a new discussion. I didn't find my answer in that thread, I've already tried that.
I'm still having this issue as well. Over a year and a half later, and Adobe users are still having this issue.
the same issue on my system. To stop and restart cc helps for a short period, but it occurs again.
What is the main task of that SW CEF helper? Is ther any need for a continous run?
What about some statements in the web, it could be a trojan?
Sheena, as you can see from all the threads, this issue has not been addressed to our satisfaction. We all have the latest software, well beyond the version that the link you gave says it was fixed in. Now, granted, it's much less. I'm only having 3-4% of my CPU time sapped away by CEF Helper instead of 20-30% like before, but 3 to 4% is still too much. It noticeably slows down my PC.
What the heck is it doing anyway? Why should it be necessary to sap away 4% of my power when I haven't even manually launched Cloud or Photoshop or any other adobe product (except Flash which run in the browser on some web pages)? If it's just to "call home" and check in with the Adobe server, why can't it do that in a microsecond? Why does it have to do it continually even when Photoshop is not even running?
Your second link says it might be a virus. I don't trust that link one bit. It has horrible English and for all I know could be written by criminals looking to install their own ransomware.
