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?
