Avast Cleanup Premium is an optimization tool that scans your PC to identify unnecessary items and performance issues, freeing up disk space and improving the speed of your system. After installing Avast Cleanup Premium, some users may have an issue with an unresponsive program. This may occur as a result of the program unintentionally being put to sleep during the initial Avast Cleanup Premium setup process.
To resolve the issue:
Open Avast Cleanup Premium, hover your mouse over the side menu, then select Sleep Mode. 
Click the slider next to the program you want to use to turn it from gray (Off) to green (On). 
The issue should now be resolved. If the program you want to use still doesn't open, contact Avast Support for further assistance.
