Hi,
I chance the AV from avast free to the avira free and ccleaner does not run like before it appears an empty screen just the window of the program no letters inside. I run like that a couple of time and always have the same respond.
Then I run the program as administrator and it works fine.
Is it normal?
Even the avira needs admin right for execute!
Need to reinstall the ccleaner?
Sorry about my English
