Well done Nergal - Unchecking the "AVG Utilities" in "Applications" seems to have worked fine. The AVG Utilities files were being deleted every time I ran CCleaner. Many thanks for your help. Great Forum.
When I run CCleaner 2.28.1091 it finds 64MB (20 files) of AVG Anti-Virus to be deleted as "Utilities". Is this normal? I have a slow Broadband and wonder if these files need to be found and deleted. Any advice appreciated.
