[CCleaner stopped working]

Thanks for that Fred.

What happens if you pause or turn your McAfee off for a moment to try running CCleaner, or make CCleaner an exception in McAffee?

If there is a bug and it's not just a question of the AV's needing to update their definitions for the new version, then the more information we can gather the more the developers will have to work with.

I just paused McAfee. CCleaner will still not respond. Clicking the CCleaner icon briefly gives the "loading circle" icon for a second or two and then it stops without loading.

The other Piriform programs (Speccy, Recuva etc) still open and work fine.

Thanks.

My CCleaner Pro has also stopped working. I have McAfee AV not TrendMicro. 

I have CCleaner Pro and McAfee. My OS is Windows 7 pro updated by 0Patch Pro.

Just noticed yesterday that ccleaner has stopped working. I had it on automatic clean at the closing of the browser. Not only does it no longer do the automatic clean but clicking on the CCleaner icon will not open or activate the program. I have tried downloading the latest version and re-installing it but the problem continues with no change. 

Any advice or information is appreciated.
