CCleaner not running

I installed the latest version (5.75) of the app on my laptop but wasn't able to launch it (windows 10 Pro). The instalation process goes without any problem but after when I click on the icon nothing happens. It's the same if I try to launch the app from the bucket menu.

This is usually caused by your antivirus blocking the new CCleaner version.

Sometimes it can take certain AV's a week or so to update definitions and recognise the new CCleaner version.

What antivirus are you using and is it up to date?
