Traumatised

And it is now running fine after a restart. Thank you.

Works in safe mode.

3% is internet explorer history. Haven't tried to run it in safe mode yet. I shall try that later today and let you know. Thanks.

I have been using computers since the "Pegasus Autocode" {!) and ccleaner for years, and never had a problem until the last two releases. I am presently running a tower, laptop and Lenovo MIIX 310 notebook, all running win10 and, all with ccleaner. The tower and laptop run ccleaner fine but ccleaner on the Lenovo sticks at 3%. I have uninstalled then reinstalled and the first run was fine but after that it reverts to sticking at 3%. Cancel doesn't work and I end up closing it from the task master. Anyone got any ideas?
