[Unwanted plug-ins]

At the end of my working day, sometimes more often, I delete unwanted cookies from my computer (iMac), also clear cache and history, using CCleaner; 

 

Yesterday, after deleting, I noticed that the number of cookies and other website data exceeded the number I keep. When I checked manually, I found that the extra items were all plug-ins of some sort from sites I'd not heard of.  

 

DAK please whether websites can install plug-ins without the user's consent and if so is a a new trend to get round the cookie law?  In any event whether CCleaner can do this or another app that can delete them without my having to do so manually? 

 

Thank you. 

[CCleaner not working properly with El Capitan]

Same problem for me, no cookies showing. Brand new iMac, running EC.  

 

Works beautifully on my other iMac, Snow Leopard.

 

Wish I'd known about CC long ago, wouldn't wasted money/time on MacKeeper! 

 

I shall probably upgrade to pro version once this EC bug is resolved.
