Go to “Advanced settings”, then click on “Browser protection” on the left, in the “Safe banking and web browsing” section, scroll down and there is the item “List of allowed files in browser protection”. Click on “Change”. A window with exceptions for this function will open. In this window, click on the “Add” button and in the next smaller window, enter the path where you have CCleaner stored in the line that appears (e.g. E:\CCleaner\CCleaner64.exe). Of course, adjust the path to the exe file according to your actual path. Then click on all the “OK” buttons to save the changes.
